Ultrafast dynamics in dimeric hemoglobin probed by time-resolved resonance Raman spectroscopy

Time-resolved anti-Stokes Raman spectroscopy is selective for vibrationally excited modes, and it is therefore a powerful method for measuring vibrational energy relaxation.1-2 The intensity ratio of anti-Stokes and Stokes scattering is expected to provide the most direct information about relative...
