Charge transfer between ND3+(nu(+)(2)) and phenol

Reactions of vibrationally state-selected ND3+ with phenol were studied in a guided beam arrangement. There are four exoergic channels, of which only charge transfer (CT) has significant intensity. The dominant mechanism requ ires intimate collisions, with little long-range electron hopping. Despite the presence of deep hydrogen-bonded wells, only a few percent of collision s form long-lived complexes. ND3+ vibration has no effect on CT at low ener gies, with weak inhibition at high energies. Charge transfer with H/D excha nge is a minor channel, inhibited by ND3+ vibration and collision energy. T he small vibrational effects are in contrast to the large effects observed in reaction of PhOH+(nu (6a),nu (12)) with ND3. (C) 2000 American Institute of Physics. [S0021-9606(00)01035-7].
