Inelastic scattering of vibrationally excited KBr by small polar molecules

Scattering intensities as functions of angle and velocity, for the interaction of highly vibrationatly excited potassium bromide with methanol, water, and ammonia under molecular beam conditions, are reported and analyzed. A crossed beam reaction is used to produce potassium bromide with an average vibrational energy of 41 kcal/mole. Inelastic collisions between excited potassium bromide and partner molecules occur with large cross sections, > 300 A(2), and proceed through a short lived energy randomizing collision complex.
