Abstract

Time-resolved Raman and adsorption spectroscopies were used to characterize the vibrational and electronic structure of the *B_1g excited state of nickel(II) protoporphyrin IX dimethyl ester. Evidence for structural relaxation processes within the initial B_1g excited state was observed on picosecond time scales. We conclude that interconversions between structural conformers are important in these processes. Such conformational interconversions in metalloporphyrins may have a major role in the complex mechanisms of many biological systems.
