Our protocol then combines the explicit calculation of individual A and B terms in regions of well-separated electronic transitions with damped response calculations of the MCD signal in dense spectral regions. This opens for the investigation of the MCD of molecules in a broad frequency range including cases with degenerate excited states. Furthermore, the implementation of damped quadratic response can straightforwardly be extended to compute other perturbation-induced spectra such as NSCD and MChD.
