|Abstract: ||Fluorescence line narrowing spectra of the diprotonated forms of the porphine have been obtained in solid acid solutions
at liquid helium temperature. Quantum-chemical calculations of frequencies and forms of in-plane and out-of-plane
vibrations for the diprotonated forms were also performed. The manifestation of intense vibronic transitions in the fineline
fluorescence spectra of diprotonated forms of Н2P with participation of out-of-plane modes have been estimated
on the basis of mutual analysis of the experimental data and the results of quantum chemical calculations. The reason
for the spectral activation of out-of-plane modes consists in saddle distortion of the porphine molecule upon formation
of the diprotonated form.|
