Traditional identification methods are often considered inefficient and subjective, while existing spectral techniques are hindered by complex preprocessing procedures and limited model interpretability. To address these limitations, an efficient and interpretable approach was developed by integrating Raman hyperspectral imaging with deep learning techniques. First, a segmentation framework, One-Target Hyperspectral Image Segmentation and Extraction based on the Segment Anything Model, was developed to efficiently and reliably extract regions of interest from wheat grains in Raman hyperspectral images. Subsequently, Raman characteristic peaks were selected using chemical prior knowledge, rather than traditional data-driven methods that rely on statistical features, to enhance the chemical interpretability of the features. Finally, a Raman Spectral Attention Network was designed by incorporating multiscale feature extraction and a Transformer module to improve the modeling performance on the selected Raman characteristic peaks. Experimental results demonstrated that the segmentation framework significantly improved preprocessing efficiency, while Raman Spectral Attention Network achieved an accuracy of up to 99 % in classifying eight wheat varieties. Overall, this study provides a reliable, interpretable, and efficient solution for wheat variety identification, with promising applications in food quality assessment, precision agriculture, and food safety monitoring.</div></div>","PeriodicalId":433,"journal":{"name":"Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy","volume":"344 ","pages":"Article 126722"},"PeriodicalIF":4.3,"publicationDate":"2025-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With UV–Vis spectroscopy, we observed a degradation product which absorbs around 450 nm. The degradation accelerated strongly at alkaline pH (&gt;8.5) and in the presence of a buffer, particularly PBS. We performed NMR and stimulated Raman studies to identify the degradation product and analysed the degradation kinetics. With both methods, we observed H → D isotope exchange at the methyl group linked to the imidazole group of YM155, after dissolving YM155 in D₂O. The exchange was similarly both alkaline- and buffer-catalysed. We were unable to identify the 450 nm-absorbing product of the degradation neither by NMR nor stimulated Raman, yet our studies pointed at imidazole-linked methyl as being associated with the YM155 degradation. The alkaline degradation of YM155 could be related to its mechanism of action – binding to DNA in mitochondria with pH values above 8.</div></div>","PeriodicalId":433,"journal":{"name":"Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy","volume":"344 ","pages":"Article 126720"},"PeriodicalIF":4.3,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144703999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the inherent trade-off between luminescent efficiency and luminescent dissymmetry factor (g_lum) has significantly limited the diversity of high-performance CP-TADF materials. In this study, we systematically investigated the luminescent mechanism of a reported thermally activated delayed fluorescence molecule QAO using density functional theory (DFT) and time-dependent DFT (TD-DFT) methods coupled with the thermal vibration correlation function (TVCF) approach. Through calculations of intersystem crossing rates, reverse intersystem crossing rates, radiative decay rates, and non-radiative decay rates, we confirmed the TADF characteristics of QAO. Moreover, the evaluation of electronic circular dichroism (ECD) spectrum and g_lum values (1.92 × 10⁻³) confirmed the circularly polarized luminescent (CPL) feature. Furthermore, based on these findings, two strategies (introducing chiral unit and extending the acceptor unit) were proposed to enhanced the CPL and TADF properties, and two new efficient CP-TADF molecules (QAO-Cz and QAO-CzNCF) were constructed. Results indicate that the g_lum values of QAO-Cz (4.06 × 10⁻³) and QAO-CzNCF (4.46 × 10⁻³) were largely improved compared with that of initial QAO with decreased electric transition dipole moment (|μ|) and magnetic transition dipole moment (|m|) of the molecules. Compared to |m| (0.723 × 10⁻²⁰ erg·G⁻¹, 0.474 × 10⁻²⁰ erg·G⁻¹, 0.349 × 10⁻²⁰ erg·G⁻¹), |μ| (3.885 × 10⁻¹⁸ esu·cm, 1.242 × 10⁻¹⁸ esu·cm, 0.786 × 10⁻¹⁸ esu·cm) exhibits a greater degree of reduction, leading to an enhancement in |m|/|μ| and g_lum values and further improving the CPL performance. Meanwhile, the energy gap of the molecules QAO-Cz (0.03 eV) and QAO-CzNCF (0.05 eV) are significantly reduced compared to QAO (0.14 eV), while the spin-orbit coupling values are remarkably increased, ensuring the excellent TADF properties of these molecules. Thus, the fundamental structure-property relationship is revealed and inner luminescent mechanism is illustrated. Wise strategy for designing CP-TADF molecules is proposed, and both designed CP-TADF molecules successfully achieve synergistic optimization of CPL and TADF properties, this work provides new insights for developing high-performance CP-TADF emitters.</div></div>","PeriodicalId":433,"journal":{"name":"Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy","volume":"344 ","pages":"Article 126710"},"PeriodicalIF":4.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synchronous fluorescence matrices (SFMs) created by changing both the excitation and the offset do not exhibit any bilinear characteristics, unlike excitation-emission matrices (EEMs), impeding their use with multilinear techniques. This work proposes a new generalized algorithm for converting any SFMs into EEMs in a quick and efficient manner without distortions while minimizing empty spaces, joining the instrumental advantages of SFMs with the data processing advantages of EEMs. The proposed algorithm obtained consistent EEMs from SFMs, whose data arrangement will be determined solely by the ratio of the offset and excitation steps. SFM datasets of PAHs at different step ratios were measured and their PARAFAC models were used to assess its usability and compare it with a previously proposed algorithm. CORCONDIA values confirmed model trilinearity (between 74 and 99 %) and instrumental profiles were recovered; however, results varied with different step ratios. In matrices where the excitation step was a multiple of the offset step, the conversion was equivalent to a shearing transformation, yielding better deconvoluted profiles when compared with others, which could produce grid-like patterns complicating visual identification of some components. While this points to an optimal application of it being made with those specific step ratios, the algorithm also provides legacy support for datasets measured differently. The algorithm development allowed the use of any SFM datasets with bilinear/trilinear algorithms able to handle empty spaces, without the limitations of previously suggested conversion algorithms.</div></div>","PeriodicalId":433,"journal":{"name":"Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy","volume":"344 ","pages":"Article 126692"},"PeriodicalIF":4.3,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144685666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
