Title: Investigations of Heme Protein Absorption Line Shapes,
　        　Vibrational Relaxation, and Resonance Raman Scattering
　           on Ultrafast Time Scales

Abstract:
　　The spectral dynamics of photoexcited myoglobin (Mb) and its
　ligand species have been measured using both single wavelength
　and broadband continuum probes. Ultrafast spectral relaxation
　of the deoxy photoproduct involves an initially broadened and
　red-shifted absorption band. These results are consistent with
　an immediate (sub 100 fs) relaxation to the electronic ground
　state followed by vibrational equilibration.
