A Method of Calculating Cross Sections for Molecular Collisions: October, 1954 (Classic Reprint) - Softcover

Inhaltsangabe

A practical guide to calculating cross sections for slow, inelastic molecular collisions. This work presents a relatively fast method for determining how energy transfers between molecular vibrational modes and translational motion occur during collisions, using a perturbation approach and an impact-parameter framework.

Written for researchers and students in physical chemistry and chemical physics, the book balances theory with workable techniques. It acknowledges the challenges of modeling intermolecular potentials and translational motion while offering a tractable path to quantitative results in cases where traditional Born-approximation methods fail.

• Learn how to set up a translational–internal system with a clear separation of degrees of freedom and a perturbation that couples them.


• See how the WKB method can be applied in an impact-parameter formulation to compute cross sections.


• Understand how to treat short-range perturbations and turn-point regions, focusing on the region where the interaction is strongest.


• Explore the distinction between classical and quantum limits and how they affect the calculated cross sections.

Ideal for readers of advanced molecular collision theory, quantum mechanics in gases, and statistical models of intermolecular forces.
