Transient Raman Spectroscopy of Isotope-Substituted Species of Bacteriochlorophyll a, Bacteriopheophytin a And Chlorophyll a: Changes in the Bond Orders in the Macrocycles Upon Triplet and Singlet Excitation
The S0, T1 and S1 Raman spectra of bacteriochlorophyll a, bacteriopheophytin a and chlorophyll a were recorded for the species of natural abundance isotopic composition and those of totally substituted with 15N, 13C and 2H isotopes. Based on empirical assignments of the Raman lines, changes in the bond orders in the macrocycle upon triplet and singlet excitation are discussed.
