## Abstract The chemical tropospheric dimethyl sulfide (DMS, CH~3~SCH~3~) degradation involves several steps highly dependent on the environmental conditions. So, intensive efforts have been devoted during the last years to enhance the understanding of the DMS oxidation mechanism under different co

โฆ Synopsis
An error was discovered in the method used for calculating the moments of inertia for the internal rotations in the activated complex. In order to retain good agreement between theory and experiment, it was necessary to change some other molecular parameters of the activated complex. The following changes accomplish this; they are also more consistent with other, independent data.
- The C-H-0 bond angle is assumed to be 160" rather than 135". This is closer to the angle of 165" calculated by Walch and Dunning [l] for the

## Abstract Rate coefficients for the reaction of the hydroxyl radical with CF~3~CH~2~CH~3~ (HFCโ263fb) were computed using __ab initio__ methods, viz. MP2, G3MP2, and G3B3 theories between 200 and 400 K. Structures of the reactants in the ground state (GS) and transition state (TS) were optimized
## Abstract Rate coefficients are reported for the gas phase reaction of OH with OClO over the temperature range 242โ392 K at 25, 50, and 100 Torr (He). Kinetic measurements were made using pulsed laser photolysis with laser induced fluorescence detection of the OH radical. The measured rate coeffi
