Paper Abstract

The spectra of porphyrin isolated in low temperature noble gas and nitrogen matrices reveal a multiplet structure consisting of pairs of sites (A and B) which may be interconverted as a result of photo-induced double proton transfer. Single-site spectra are obtained for IR, electronic absorption, fluorescence and phosphorescence. Analysis of different magnitudes and signs of site-splittings in the IR spectra may be helpful for vibrational assignments.
