Abstract

have been measured by the discharge-flow technique to be 2.6·10-32, 6.1·10-32, and 6.4·10-31 cm6s-1 respectively.

ChemInform Abstract

have been measured by the discharge-flow technique to be 2.6·10-32, 6.1·10-32, and 6.4·10-31 cm6s-1 respectively. Although the rates for He and N2 can be rationalized in terms of existing theory, that for H2O implies a collision efficiency greater than 1. This can be rectified by use of the total quantum mechanical cross section instead of the Lennard-Jones cross section.
