Picosecond timescale Raman processes and spectroscopy

Abstract

Time resolved properties of vibrational states of molecules on the picosecond scale are surveyed using both conventional spontaneous Raman effects as well as coherent Raman processes. In certain respects the coherent signal methods have been found to have distinct advantages related to their intrinsic time gating capability but they can have disadvantages in the form of nonresonant background interference. New picosecond time resolved Raman spectra of excited states and of myoglobins are presented. © 1985, IUPAC.
