Title: | Transformations in the fluorescence line narrowing spectra of porphin upon the formation of diprotonated species | Authors: | Starukhin, S. Alexander Kruk, Mikalai M. Gladkova, Olga L. MAES, Wouter |
Issue Date: | 2011 | Source: | Macroheterocycles, 4(2), p. 85-88 | 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. | Keywords: | Porphine; fluorescence line narrowing spectra; diprotonated form; saddle conformation | Document URI: | http://hdl.handle.net/1942/13034 | ISSN: | 1998-9539 | e-ISSN: | 1998-9539 | ISI #: | 000209017200003 | Category: | A1 | Type: | Journal Contribution |
