Sažetak

The electron impact induced fragmentation of four 1,3-diphenyl-
2-pyrazolines substituted in the para. position of the 3-phenyl
with a phenyl, phenoxy, thiophenoxy or benzoyl group was studied
by analyzing metastable peaks and by accurate mass measurements.
In general, the fragmentation was found to be in accord with that
of 1,3-diphenyl- 2-pyrazoline. Some characteristic features in their
mass spectra are caused by hydrogen migrations and skeleton
rearrangements.
