Abstract
Abstract Electronically excited nitrogen fluoride is formed by reacting fluorine atoms with azide radicals according to the reaction: F+N.sub.3 →NF*+N.sub.2. in a preferred embodiment, the azide radical is provided by using HN 3 , and the atomic F is formed by discharging microwaves through either F 2 or CF 4 , or by thermally decomposing F 2 .
