Frequency shifts: The influence of the local electrostatic environment on the ground vibrational level of photodissociated CO in native myoglobin is investigated by performing QM/MM calculations at the DFT level. The distribution of CO frequencies in the FeCO conformation occurs at higher wavenumbers than in the FeOC conformation (see figure).
