Abstract : Research has been done with pulsed-laser evaporated B, Be and Mg atoms and molecular hydrogen to explore the reactivities of these metals with H2 and to investigate infrared spectra of the product molecules in solid argon. The major products in the B/H2 system were BH, (H2(BH), Bh3, (H2) (BH3) and B2H6. It is clear that molecular hydrogen is complexed to BH and BH3 in these experiments. Pulsed laser ablated boron atoms have been reacted with NH3, CH3NH2 and NO to form novel boron insertion products which have been trapped in solid argon for infrared spectroscopic study. This work makes two important contributions. First, laser ablated boron atoms are shown to be highly reactive. Second, the importance of isotopic substitution for matching experimental observed and theoretical calculated frequencies for new molecules is clearly demonstrated.
