## Evwnsive calculalions of cross seclions and rnle constants Ior rotational excilalion of ammonia colliding with He and H2 on nb inirio polenriel energy surfaces are cnrried CIUI using a srmicl~ssical collision model.
A tunable dye laser was used to populate selectively a single rotational-vibrational state of N 2 ( B 'E , u' = 0, N' = O-l 5 ) . The population changes induced by collisions with He were determined using time-resolved spectroscopy in a flowing afterglow experiment. Total rotational transfer rates f
A discussion of reactants vibrational energy and temperature dependence of reactive rate constants for the hydrogen atom hydrogen molecule reaction is presented for a matrix of values calculated at 0 < u < 10 and temperatures in the range from 300 K to 4000 K. A parametrization of the results is att
