The conducted density functional theory calculations show that introducing high concentrations of impurity atoms (6.3% and 12.5% of the number of carbon atoms) into the diamane structure has almost no effect on the lattice constant but significantly changes the band gap: it increases by 0.97 eV upon the introduction of nitrogen atoms, decreases by 0.94 eV upon the introduction of boron atoms, and decreases by 0.82 eV upon the simultaneous introduction of both atoms. These structural and electronic properties suggest that boron- and nitrogen-doped diamanes can be used in the synthesis of lateral heterostructures for the production of nanoelectronic devices. The recorded Raman and IR spectra can be used to identify doped diamanes by means of characteristic vibrational modes of boron and nitrogen atoms inside the diamane crystal lattice.</p>","PeriodicalId":668,"journal":{"name":"Journal of Structural Chemistry","volume":"66 2","pages":"230 - 239"},"PeriodicalIF":1.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ionization of the initial molecule with the formation of the dicationic state corresponds to the Auger decay. If molecules of the nearest environment are ionized, then it is the intermolecular Coulombic decay (ICD). Recent studies show that intermolecular interactions, including those with a solvent, are an important factor determining the probability of such relaxation processes and their energy characteristics. DNA and RNA nucleic bases are known to have some amount of water molecules in their nearest environments. In this work, using the equation-of-motion method in the EOM-DIP-CCSD variant, we consider the effect of the number of water molecules and their orientations in uracil complexes (U) U–<i>n</i>H<sub>2</sub>O, <i>n</i> = 1-4 on the spectrum of dicationic states formed by the described processes. It is shown that the lowest energies of ICD states are due to water coordination to uracil at positions most characteristic of RNA.

The number of ICD dicationic states increases with increasing number of environment molecules, which indicates the significant role of nonlocal decays in solution.</p>","PeriodicalId":668,"journal":{"name":"Journal of Structural Chemistry","volume":"66 2","pages":"240 - 250"},"PeriodicalIF":1.2,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
