✦ Synopsis

Excimer laser photolysis of diborane and laser-induced fluorescence of BH have been used to measure rate constants for the reactions of BH with NO and C:H, at total pressures near 1 Torr, over the temperature range 250-350 K. Upper limits were obtained for the rate constants for reactions of BH with 01, CO, CHI, and C2H6. Experiments with different buffer gases show no effects that can be attributed to the buffer gas acting as a third-body during adduct formation. For the BH t NO reaction the results are consistent with a model in which an intermediate HBON*, formed by capture over the centrifugal barrier in a dipoledipole potential, rearranges in a time of the order of a picosecond to give the products BO and NH.
