Infrared Spectra of NF, NCl, and NBr

Abstract
The infrared spectra of FN3, ClN3, and BrN3 suspended in Ar and N2 matrices have been observed at 4° and at 20°K. Ultraviolet photolysis of these systems results in the appearance of absorptions assigned to the free radicals NF, NCl, and NBr. Evidence is presented for the matrix deactivation of NBr to its ground 3Σ state. Slow photolytic decomposition of NCl and NBr has been observed. Possible mechanisms are discussed for the origin of a green phosphorescence identified as resulting from N atoms trapped in the matrix.
