REMARKS - Considering the relatively small size of this molecule, the spectrum is unusually complex indicating the occurrence of complicated fragmentation pathways. With the exception of the H2S+" ion at m/z 34 the identity and origin of most of the peaks is as yet unknown. Nevertheless the marked peak series at m/z 34, 71, 74, 88, 100 and 115 is highly characteristic for all penicillins thus far analysed.
