Deuterium isotope effects and mechanism of the gas phase reaction [C3H7]+→[C3H5]+ + H2

The deuterium kinetic isotope effect and the deuterium isotope effect upon kinetic energy release have been calculated for the loss of H₂ from the C₃H₇]⁺ ion. The calculations are based on the transition state structure suggested recently from ab initio calculations on the reaction pathway. The results obtained are in good agreement with experimental data.
