Rotational velocity, vibrational analysis

Gillen et al. [67] estimated the distribution of c.m. recoil energies from the velocity analysis. No significant differences were observed in scattering from K + HBr and from K + DBr, and E mp was approximately 1.5 kcal/mole (0.06 eV). Electric deflection analysis [34, 35] on MBr from K (and Cs) + HBr indicates that (IFr ot) = 1.5 kcal/mole (0.06 eV) and confirms that the rotational momentum of KBr is approximately equal to the orbital momentum of the reactive collisions [see equation (43)]. These measurements suggest that a considerable fraction of the small amount of energy available in this reaction enters the KBr vibration. 

A large number of polyatomic halides H- alkali and alkaline earth metal atom reactions have been studied by angular and velocity analysis in molecular-beam experiments and by laser-induced fluorescence analysis of the vibrational and rotational distributions in beam-gas experiments. In the beam studies of and + CH3I, K + + CH3NO2,...
