ResumoAbstract The mass spectra of 25 triphenylmethyl (trityl) substituted compounds have been recorded. The trityl cation m/e 243 appears as a peak of major intensity for all classes of compounds examined; these contained trityl‐carbon, trityl‐nitrogen, trityl‐oxygen or trityl‐sulfur bonds. Fragmentation of the non‐trityl portion of the molecules produced simple ions whose origin was predictable or of low intensity. A mechanism for the decay of the trityl cation is presented which is based upon retention of the α‐carbon. Supporting evidence was afforded by mass spectral analysis of (C 6 H 5 ) 3 13 CH in which all fragments from the trityl cation appear to retain nearly all of the 13 C.
