the incident energy of O from 5 to 1 eV. With 5.0 eV incident energy, the OH
rotational distribution peaks around

5-6 and has a bit of a Boltzmann-like
distribution. On the other hand, with 1 eV incident energy the OH rotational
distribution is hotter and peaks around

10-12. This is further evidence that
the transfer of energy into the product states is not governed by the incident energy.
Comparing translational energy distributions provides another contrast of the
results from F vs O. Here we compare the H abstraction products (OH and HF) as
well as the inelastic scattered atoms (O and F). For both inelastically scattered
products there is a similar variation of final translation energy distribution with
respect to angle of incidence. At 60
angle of incidence there is a broad distribu-
tion of translational energies, covering the range from almost zero energy to an
energy equal to the incident energy (i.e., 1.0 eV for F and 5.0 eV for O) as shown in
Figs.
5
and
6
. By contrast, at 30
angle of incidence, most of the input translational
energy is transferred into the liquid.
There is a notable difference in the final translation energy of the H abstraction
products, OH and HF. The OH final translational energies are very similar to the O
energies and still have a distinctive variation with respect to the incidence angle.
In contrast, the HF product final translational energies are largely independent of
