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.
