 Title: THE HIGH RESOLUTION SPECTRUM OF THE $4^{1}{_{0}}$ BAND OF THE UNSTABLE MOLECULE $H_{2}NBH_{2}$ NEAR $7.5 \mu$m Creators: Gerry, Michael C. L.; Lewis-Bevan, W.; Merer, A. J.; Westwood, N. P. C. Issue Date: 1984 Publisher: Ohio State University Abstract: Aminoborane, $H_{2}NBH_{2}$, an inorganic analogue of ethylene, has only been positively observed in the gas phase by microwave $spectroscopy^{1}$ after pyrolysis of $B_{2}H_{6}/NH_{3}$ mixtures. Using an alternative route we now report that this unstable molecule can be prepared in excellent yield in the gas phase, thereby permitting all 9 of the 11 infrared active fundamentals between 800 and $4000 cm^{-1}$ to be observed together with several combination bands. The spectra, recorded on a Bomen DA3.002 FTIR spectrometer, exhibit a wealth of rotational structure and indicate severe perturbations within several of the bands. A detailed analysis of the observed bands is being carried out, starting with the $4^{1}_{0}$ BN stretching frequency. Description: $^{1}$ M. Sugie, H. Takeo and C. Matsumura, Chem. Phys.
