title: [Fine structure of the fluorescence spectra of chlorophyll a, protochlorophyll, and their pheophytins following selective laser irradiation].
abstract: Fine structure fluorescence spectra of solutions in diethyl ether of chlorophyll a, pheophytin a, protochlorophyll and protopheophytin were obtained and studied at 4.2 K under stimulation with reconstructed laser on dyes. Dependence of the spectrum on lambda excit was studied and oscillation frequencies in basic and excited electron states were determined. Frequency dependence on the character of molecular surrounding was exemplified by chlorophyll a.
