Abstract
In this paper EI mass spectra, HREI data and 13 C NMR(COM.INEPT) data of a new Calcium Antagonist Nimodipine were measured. Mass spectra fragmentation of characteristic fragment ions were discussed on the basis of High resolution mass spectra data. Some of fragment ions probably results in Mclafferty rearrangment.
