Broad-band and single-wavelength photolysis studies of NFCl2 and NF2Cl in low-temperature argon matrices have been carried out and the photolysis products identified via the IR spectra of the matrices.The photolysis energies were chosen on the basis of the UV absorption spectra, which for both compounds consist of single broad structureless features at 270 nm for NFCl2 and at 230 nm for NF2Cl.Broad-band photolysis and photolysis at 250, 270, and 300 nm of the NFCl2 matrix produced NF, as identified by the appearance of a peak at 1113 cm^-1 in the IR spectrum.Photolysis of the NFCl2/Ar matrix at 210 and at 330 nm and of the NF2Cl/Ar matrix at 210, 245, and 330 nm produced no changes in the IR spectrum.Mechanisms are presented to explain these results.
