摘要

我们展示了呋喃的质量相关旋转排列光谱和首个高分辨率旋转拉曼光谱。光谱的测量范围高达 0.5 THz，分辨率低至 1.6 MHz。13C 和 18O 同素异形体的光谱是在自然丰度的相应质量通道中观测到的。根据我们的数据和文献常数，我们对呋喃的有效结构和平衡结构进行了纯实验结构分析。结果凸显了 CRASY 在没有同位素富集样品的情况下获得稀有同位素光谱的实用性。

Mass-correlated rotational Raman spectra and the structure of furan

We present mass-correlated rotational alignment spectroscopy and the first high-resolution rotational Raman spectra for furan. Spectra were measured with a spectral range up to 0.5 THz and a resolution down to 1.6 MHz. Spectra for ¹³C and ¹⁸O isotopologues were observed in their corresponding mass channels at natural abundance. Based on our data and literature constants, we performed a purely experimental structure analysis for the effective and equilibrium structures of furan. The results highlight the utility of CRASY to obtain rare isotopologue spectra without isotopically enriched samples.

期刊介绍： The Journal of Raman Spectroscopy is an international journal dedicated to the publication of original research at the cutting edge of all areas of science and technology related to Raman spectroscopy. The journal seeks to be the central forum for documenting the evolution of the broadly-defined field of Raman spectroscopy that includes an increasing number of rapidly developing techniques and an ever-widening array of interdisciplinary applications. Such topics include time-resolved, coherent and non-linear Raman spectroscopies, nanostructure-based surface-enhanced and tip-enhanced Raman spectroscopies of molecules, resonance Raman to investigate the structure-function relationships and dynamics of biological molecules, linear and nonlinear Raman imaging and microscopy, biomedical applications of Raman, theoretical formalism and advances in quantum computational methodology of all forms of Raman scattering, Raman spectroscopy in archaeology and art, advances in remote Raman sensing and industrial applications, and Raman optical activity of all classes of chiral molecules.
