| Abstract: | The routine mass spectra of ten 2- (4' -substituted styryl ) phenyl-5- (4"-biphenyl ) oxa-zole compounds were measured. Their MS fragmentation patterns have been interpretedon the basis of looking for the daughter ions from the parent ions by means of EI linkedscan. The formation mechanisms of same fragment ions and effect the substituent groupon the relative aboudance of the ion peaks have also been studied. |
