Ultrafast spectroscopy of the ferrous-NO cyt. c/CL adduct. The spectral evolution at selected delay times of the ferrous-NO cyt. c/CL adduct upon photodissociation of the NO is presented as a series of difference spectra using the spectrum of the NO form as a baseline. Inset I, spectral contribution of a 7-ps component (see “Results” for assignment). Inset II, the calculated static absorption spectrum of the 4-coordinated heme calculated (see “Results” for assignment). Inset III, a fit to the kinetic trace at 427 nm.
