The possible contribution of internal degrees of freedom to the activation of simple bimolecular reactions is discussed in terms of a classical model; it is suggested that existing experimental data on the reactions of halogen atoms with isobutane an

Several recent computational studies have predicted the possible formation in combustion systems of the unknown species H–NO2, iso-nitrous acid. We report here high-level calculations of the harmonic vibration frequencies as an aid to identificatio

A general solution to the one-dimensional time-independent Schrodinger equation is derived using the properties of the Laplace transform. The derivation assumes that the potential func- tion is real and that it can be expressed as a Fourier series wi

Classically, the evolution of a physical system is described by a unique trajectory in an appropriate phase space. Ehrenfest’s theorem suggests the possibility of similar description in terms of the expected values of the position and momentum obse

Beginning with the conjecture that the principal difference between weakand strong-collision reactions is intrinsic to the reactant molecule, rather than in the nature of the collisions between molecules, a reanalysis of the unimolecular falloff phen

It is shown that there will be strong orienting effects in the collision of two radicals which will invalidate attempts to calculate disproportionation–recombination ratios by simple geometric arguments.

The master equation is solved analytically for the ionization in a dense hydrogen plasma involving single-quantum transitions. The derived expression for the observed ionization rate coefficient is valid for all temperatures at which the ionization t
