Cytochrome c: A Multifunctional Protein Combining Conformational Rigidity with Flexibility

Table 1

Listing of B-band spectral parameters of ferri- and ferrocytochrome derivatives inferred from a vibronic analysis of the respective CD and absorption band profile: : electronic (Stark) splitting, : vibronic splitting, : wavenumber associated the average transition energy of the split B-band, and and : Lorentzian and Gaussian halfwidths of the Voigtian B-band profile. Taken from [37].
