Our work brings the following advances. First, we clean the SMILES51reported in Grambowet al42. The original publication treated all reactions with multiple products as containing one product complex, which does not conform well with traditional TST calculations that expect partition functions for each...
Quantum chemistry calculations with density functional theory, conventional transition state theory and Wigner's tunneling effect correction are employed to estimate the rate constants of four important chemical reactions: F+SO2F鈫扴O2F2, F2+SO2鈫扴O2F2, SO2F+SF5鈫扴F6+SO2and SOF3+SF3鈫扴F4+...

Rate coefficients for the reaction of OH with CF3CH2CH3 (HFC-263fb) between 200 and 400 K: ab initio, DFT, and transition state theory calculations. Rate coefficients for the reaction of the hydroxyl radical with CF3CH2CH3 (HFC-263fb) were computed using ab initio methods, viz. MP2, ...
Reaction-Path Dynamics and Theoretical Rate Constants for the CH 3 F + Cl → HCl + CH 2 F Reaction by Direct Dynamics Method Ab initio calculations were carried out for the hydrogen abstraction reaction from fluoromethane by chlorine atom. Optimized geometries and frequencies were computed at the...
ranges agree within the error limits. However, the data below 650 K reveal a stronger curvature, i.e., leveling off with decreasing temperature, than could quantitatively be described either by conventional (CTST) or by variational transition-state theory (VTST) calculations. Chemical reactions. (...
The results are compared with previous experimental data, especially that on selective vibrational enhancement of endothermic chemical reactions, and with the results of theoretical calculations on the H+H2O reaction.doi:10.1039/a902348hBarnes, Peter W....
