The nature of the A-, B-, and C-terms that are usually used to interpret MCD spectra is more transparent with this formalism than with those in the literature. The paper concludes with a brief analysis of some literature examples.13enCoupled oscillatorMagnetic circular dichroism - MCD19980032410067
