## Abstract Reactions of Cu~2~ with several small molecules have been studied in the gas phase, under thermalized conditions at room temperature, in a fastβflow reactor. They fall into one of two categories. Cu~2~ does not react with O~2~, N~2~O, N~2~, H~2~, and CH~4~ at pressures up to 6 torr. Thi

β¦ Synopsis
The gas-phase kinetics of the reaction between Cuz and C2H4 have been studied as a function of pressure in a fast-flow reactor.
The limiting low-pressure, third-order rate constant for the reaction was found to be (9.3 + I .4) x 1 Oew cm6 s-' in He. Modeling studies of this rate constant imply that Cu2(C2H4) is bound by at least 20 kcal mol-'.

A theoretical study of interaction of ethylene with Cuz is considered using SCF/CASSCF/MP2 methods. The calculated dissociation energy is in good agreement with available experimental data. Our studies reveal that the perpendicular approach of Cu2 is more favored than the parallel approach. The stro
## Abstract Mass spectrometryβbased methods have been employed in order to study the reactions of nonβ (__h__~6~/__h__~6~), half (__d__~6~/__h__~6~), and fully (__d__~6~/__d__~6~) deuterium labeled protonated dimers of acetone in the gas phase. Neither kinetic nor thermodynamic isotope effects were
