To this end, for 19 difluoroborates as examples, we use, as a metric, the vibrational reorganization energy (lambda(vib)) that can be determined based on the computationally efficient linear coupling model (a.k.a. vertical gradient method). The reference values of were determined by employing the CC2 method combined with the cc-pVTZ basis set for a representative subset of molecules. To validate the performances of CC2, comparisons with experimental data have been carried out as well. This study shows that the vibrational reorganization energy, involving Huang-Rhys factors and normal-mode freque URL Link na plný text Kategória publikačnej činnosti ADC Číslo archívnej kópie 41480 Katal.org.

The products were identified by NMR, IR and UV-Vis spectroscopy and elemental analysis. Their electronic absorption and fluorescence band positions are affected by the character of the substituent and by the solvent polarity. The fluorescence decay of the dyes shows two lifetimes interpreted in terms of emission from two forms of the dye in the excited state. Moreover, the photochemical trans> cis isomerization is reported for these compounds. It occurs from the first excited singlet state of the trans isomer to the cis isomer following a trans-S-0> S-1 excitation. The electron-donating character of the substituent in a styrene moiety is one of the crucial factors influencing the photoisomerization process. The structure of the cis isomer was established by H-1 and N-15 NMR. Experimental studies are supported by the results of quantum chemical calculations.
