Table I.

Spectroscopic parameters measured for CYP3A4 and CYP2C9. All absorption and luminescence maxima were determined by taking the second derivative of the spectra in Figures 1 and 2. Quantum yields were measured relative to [Ru(bpy)3]Cl2 in deoxygenated water. Spectroscopic assignments are depicted in Figure 8.
