Correlation of Rates of Intramolecular Tunneling Processes, with Application to Some Group V Compounds
(The American Institute of Physics, 1960-03)
A method is presented whereby the WKB expression for tunneling frequencies permits correlation of these frequencies for members of homologous series of molecules. The necessary data required are the tunneling rate for one ...
On the Structure of Plane Detonation Waves
(The American Institute of Physics, 1960-09)
A steady planar detonation wave, considered to be a shock wave followed by a reaction zone, is studied with both irreversible and reversible first‐order reaction kinetics. A perturbation solution with first‐order transport ...
Note on the Infrared Dichroism of Axially Oriented Polymers
(The American Institute of Physics, 1960-01)
Heated Vapor Absorption Cell for Infrared Spectroscopy
(The American Institute of Physics, 1960-04)
Relative Quenching Cross Sections in the Reaction of Hg(63P1) Atoms with Isotopic N2O Molecules
(The American Institute of Physics, 1960-08)
The N14/N15 and O16/O18 isotope effects in the Hg(63P1)‐photosensitized decomposition of nitrous oxide have been measured. Observed isotopic fractionation factors, S0 (interpreted in terms of ratios of rate constants for ...
Paramagnetic‐Resonance Absorption of Ions with Spin 5/2: Mn++ in Calcite
(The American Institute of Physics, 1960-08)
The theory of the paramagnetic‐resonance absorption of ions with S = S=52 in crystalline fields of trigonal symmetry is presented. The case of manganous ions in calcite (CaCO3) is taken as an example. It is shown that the ...
Approximate Isotopic Frequency Rule and Its Application to the Spectra of Complex Molecules
(The American Institute of Physics, 1960-06)
An isotopic frequency rule is derived which is valid to a good approximation for individual modes of fully substituted hydrogen‐containing groups in a complex molecule. It is given by λi/λ = 1 — (ΣjΔTj/ρT), where λ = 4π2ν2, ...
