Title: Low-Temperature Matrix Isolation and Photolysis of BCl<sub>2</sub>N<sub>3</sub>: Spectroscopic Identification of the Photolysis Product ClBNCl
Abstract: BCl2N3 was isolated in a low-temperature argon matrix, and its FTIR spectrum was measured. Ab initio calculations were carried out to support the identification of the IR spectrum, and splitting due to the natural abundances of 10B and 11B was observed. The experimental infrared frequencies and assignments are as follows: 2170 cm-1, the N3 asymmetric stretch; 1350 cm-1, the BN stretch; 1053 cm-1, the N3 symmetric stretch; 968 cm-1, the BCl stretch. Upon UV photolysis, the BCl2N3 peaks decreased and new peaks at 2034 and 2087 cm-1 with relative integrated intensities of 4:1 appeared. Ab initio calculations were carried out and support the assignment of these features to the BN stretches in the 10B and 11B isotopomers of ClBNCl. This intermediate is consistent with the photolytic intermediate generated during the photolysis of B(N3)3, and the photolytic mechanism is discussed.
