الوصف: | Compounds with double bonds Terp-E=E′-Terp (E, E'=P, As, Sb or Bi; Terp=-C6H3-2,6 (C6H5)2) have been studied using DFT. These compounds have been used as a model for other compounds with larger substituents. Some bands of its electronic spectroscopy have been calculated using TDDFT, and the results show high correlation with experimental data, when available. In Bi-containing compounds, the origin of some weak bands in the calculated spectra and also in experimental data is unclear. An assignation of these bands is suggested, wedding the experimental data with calculated and theoretical results. These bands could be weak singlet–triplet transitions, partially allowed by spin-orbit coupling only in Bi-containing compounds. A theoretical estimation of the energy of these bands is achieved using CASSCF and MR-MP2. |
