In addition to the elimination of C 6 H 5 · and C 7 H 7 ·, 2,8‐dimethyl‐10‐phenyl‐ and 10‐( p ‐tolyl)‐phenothiaphosphines lost C 6 H 5 S· and C 7 H 7 S·, respectively from high internal energy molecular ions, while the low internal energy ions eliminated C 6 H 5 PH and C 7 H 7 PH, respectively. 2,8‐Dimethyl‐10‐phenylphenoxaphosphine lost C 6 H 5 ·, C 6 H 5 P and C 6 H 5 PH· both in the source and in the first field‐free region, but the expulsion of C 6 H 5 O· was not observed.
