    • The heme is a planar chromophore, which makes it less sensitive to the mutual orientation of pump- and probe-beam polarization. It was shown elsewhere that, for planar chromophores, the theoretical limit for anisotropy is 0.1, whereas in the case of linear chromophores, it is 0.4. Rotational depolarization can be neglected because cyt c is a protein with the heme embedded in it and such a large object cannot rotate significantly on the time scale of tens of picoseconds (Ansari et al., Biophys. J. 1993, 64, 852-868). Our ultrafast polarization measurements confirm that there is no artifact introduced by using the crossed-polarization scheme.

    • The term missing amplitude is used to indicate the difference between the measured value of the transient absorption and the maximum possible value for 100% photolysis. In this case, it is calculated from the difference of the equilibrium absorptions of the photoproduct (MP-8) and reactant (AcMet-MP-8).

    • Our photolysis calculations involve a comparison of the absorption cross sections of MbCO and cyt c at 401.5 nm. These values are taken from literature and bear some uncertainty.
