Collisional energy transfer remains an important area of uncertainty in master equation simulations. Quasi-classical trajectory (QCT) calculations were used to examine the energy transfer probability density distribution (energy transfer kernel), whi

The potential energy surface and chemical kinetics for the reaction of HO with CO, which is an important process in both combustion and atmospheric chemistry, were computed using high-level ab initio quantum chemistry in conjunction with semiclassica

In the formation of ozone by an electric discharge in molecular oxygen, substitution of 18 O and 17 O for 16 O produces equal kinetic isotope effects. This may be taken as a paradigm of non-mass dependent isotope effects. However, a number of other r

The product distribution for the title reaction was studied using our time-of-flight mass spectrometer (TOFMS) connected to a tubular flow reactor. The methyl and hydroxyl radicals were produced by an excimer laser pulse (lambda = 193 nm) photolyzing

A significant fraction (estimated to be as large as 30%) of the carbon monoxide in the atmosphere is produced by the oxidation of methane. One of the approaches that has been used to determine this fraction is an inversion of observed carbon and oxyg

Ab initio microcanonical rate constants were computed using Semi-Classical Transition State Theory (SCTST) and used in two master equation formulations (1D, depending on active energy with centrifugal corrections, and 2D, depending on total energy an

Tetrafluoromethane (CF 4 ) is an extremely stable gas which strongly absorbs infrared radiation at ∼ 8 μm, and therefore is capable of influencing the greenhouse effect. No natural sources have been identified, and the major anthropogenic source a

The electron attachment to SF{sub 6} and subsequent fragmentation of the SF{sub 6} ion to form SF{sub 5} is discussed in terms of a chemical activation mechanism resulting from the formation of the ion with an energy approximately 1 eV above the ther

We have observed the infrared emission from the products of the 193 nm photolysis of diethyl ketone (3‐pentanone) in comparison with acetone (2‐propanone) using time‐resolved Fourier transform spectroscopy. In the photolysis of diethyl ketone,

We have measured vibrational and rotational population distributions for the excited HF product of the 193 nm photolysis of CH2CF2. Approximately 15% of the available energy is released as vibrational energy of HF, and the estimated nascent HF rotati
