Reactions of Laser-Ablated Aluminum Atoms with Ammonia. Infrared Spectra of HAlNH2, AlNH2, and HAlNH in Solid Argon

Pulsed laser-ablated Al atoms react with NH 3 to give two major products, HAlNH 2 and AlNH 2, which are trapped in solid argon and identified from infrared spectra through isotopic substitution ( 15 N, D) and MP2 calculations of product structures and isotopic frequencies. The bent HAlNH molecule was a minor product.
