Detection of HBNH by infrared diode laser spectroscopy

Abstract
The infrared spectrum of a transient species HBNH was observed in the gas phase using a diode laser spectrometer. The HBNH molecule is formed in an ac discharge plasma of a diborane/ammonia or diborane/nitric oxide mixture. The ν3 band origin and the rotational constants of H11BNH were determined to be ν0=1786.193 08(72), B0=1.099 335(81), and B3=1.093 481(72) cm1, with three standard deviations in parentheses. The ν3 band of H10BNH was also observed and analyzed.
