The mass spectra of many triphenyl/tetraphenyl derivatives of the Group IV and V elements exhibit the processes [M + ˙ C 12 H 10 ] and/or [M + ˙ C 6 H 5 · C 12 H 10 ]. These fragmentations are not preceded by hydrogen scrambling between all the phenyl rings. Hydrogen scrambling does occur in certain fragment ions prior to fragmentation in both the positive and negative‐ion spectra. The process [M + ˙ C 12 H 10 ] occurs in the negative‐ion mass spectrum of tetraphenylsilane.
