Introduction to Atom-Molecule Collisions: The Interdependency of Theory and Experiment
TL;DR: For a century, since Boltzmann, it has been recognized that intermolecular collisions are primarily responsible for most observable rate phenomena, both physical and chemical, in fluid systems as mentioned in this paper.

Eine exakte klassische Behandlung der Schwingungs-Translations-Energieübertragung bei symmetrischen Zentralstößen
TL;DR: In this article, an exakte klassische Behandlung eines unelastischen Stosvorganges zwischen einem strukturlos gedachten Atom and einem beliebig angeregten vielatomigen Modellmolekul, das als System ungekoppelter Normalschwingungen beschrieben wird, diskutiert.

Unimolecular dissociations and free radical recombination reactions
TL;DR: In this paper, the steric and pressure effects associated with the recombination of free radicals both depend on the nature of the activated complex, and are therefore intimately related, from a consideration of the reverse process of unimolecular dissociation, some equations are derived for these properties using an extension of earlier transition state and quasi-unimolecular theories.

The Kinetics of the Recombination of Methyl Radicals and Iodine Atoms
TL;DR: In this article, the steric effect of pressure on the rate of free radical recombinations is investigated. But the authors focus on two main problems, namely, the magnitude of steric effects tending to reduce the rate below that calculated by the kinetic theory of collisions, and the effect of a small probability of such a process results in a reduced chance of the formation of the activated complex and thus not every collision of radical and atom is effective in producing an active molecule.

Accurate and Facile Approximation for Vibrational Energy‐Level Sums
G. Z. Whitten,B. S. Rabinovitch +1 more
TL;DR: In this paper, exact sums of harmonic vibrational energy-level densities for 45 molecules were obtained at various energies with a digital computer, and an improved "corresponding vibrational states" type of approximation was described.

The density of vibrational energy levels of polyatomic molecules
TL;DR: In this paper, the density of vibrational energy levels of polyatomic molecules is derived for both harmonic and anharmonic vibrations, and simple, approximate expressions are obtained for the density.
