As in our previous studies, 0( 3 P), generated by titration with NO of microwave discharged N 2 (He carrier), was mixed with B 10 H 14 vapor (Ar carrier) in a flow‐tube reactor. Levels of product OH were determined via LIF on an absolute basis, for dwell times 4 to 18 ms. The system was calibrated with C 2 H 6 , run under identical conditions. The reactants comprised approximately 1% of the flowing mixture. OH production is ≈62 greater from B 10 H 14 than from B 5 H 9 (under similar conditions but at somewhat lower temperature). FTIR analyses of a solid product that condensed downstream on cold surfaces showed the presence of BOH ⃜OB hydrogen bonds and matched (but not perfectly) the calculated frequencies of HB(OH) 2 . © 1994 John Wiley & Sons, Inc.
