โฆ Synopsis
The IR spectrum of the transient species HBO was observed in the gas phase using a discharge modulation method. The HBO molecule is formed in an ac discharge plasma of a BzH6/02 or BzHe/NO mixture. The vJ band origin and the rotational constants of H"B0 were determined to be uo = 1825.5610 cm -l, BO = 1.30839 cm-', and B3 = 1.29973 cm-'.
