The reaction of H3(+) with H2 in all possible deuterated combinations a VT-SIFT apparatus.The experimentally determined equilibrium constants are compared with those calculated using statistical mechanics.In general, the experimental and calculated equilibrium constants are in agreement at 300 K but differ significantly at 80 K.The discrepancy is considered in terms of nonequilibration of the reactant species at temperatures below 300 K in the VT-SIFT.
