Charge transfer and photoisomerization in 4-dimethylamino-4'nitrostilbene, and, Studies of heme proteins: The relationship between protein structure and reactivity

he quantum yield of trans to cis isomerization of trans-4-dimethylamino-4;The second chapter of this thesis is describes the application of two time resolved spectroscopic methods to examine the relationship between protein motion and ligand binding in heme proteins. Pump-probe resonance Raman spectroscopy was used to correlate changes in the Raman active Iron-Histidine mode of the heme in Myoglobin to the protein's different binding affinity for the ligands CO and O;A second technique, Pump-probe time resolved fluorescence spectroscopy was used to monitor the onset of the R-T quartenary structural change in Human Hemoglobin type A (HbA) and Carp Hemoglobin. The fluorescent emission from tryptophan...
