✦ Synopsis

The reactions for the production and removal of the three lowest electronic states of nitrogen fluoride, NF(X3Z-), NF(a 1 A), and NF(b 'Z'), are discussed from the standpoint of electron spin conservation. By invoking the Wigner-Witmer spin rule together with other spin-related properties, it is indicated that the electronically excited NF(a 'A) not only is the preferred product from the reaction of H, D, and CD3 with NF2, but should also be less reactive toward other atoms, radicals, and itself than its groundstate counterpart NF(X 35)-These conclusions are shown to be consistent with existing ex-p&mental results. Two years ago, Herbelin and Cohen [l] proposed that an addition+&nination rather than an abstraction mechanism is the reaction path between H, (D, CH,), and NF, radicals
