In this article, the concentration coefficient of viscosity of mixtures of small concentrations of organic vapour in permanent gases enables the molecular dimensions of organic molecules in the gas phase to be determined and measured with accuracy.Abstract:
Measurement of the concentration coefficient of viscosity of mixtures of small concentrations of organic vapour in permanent gases enables the molecular dimensions of organic molecules in the gas phase to be determined and measured with accuracy. The differences in size caused by chainbranching, substitutions, and other structural features are examined. The results are correlated with gas-chromatographically-determined partition coefficients of the vapours between a perfect gas phase and a solution phase in a non-polar solvent.read more

The reaction of atomic hydrogen with NO2
John E. Spencer,G.P. Glass +1 more
TL;DR: In this paper, a fast discharge flow apparatus equipped for EPR detection of radicals has been used to investigate the reaction, H + NO 2 → OH + NO, and the initial vibrational state distribution of OH was estimated as OH( v = 0): OH(v = 1): OH (v = 2)= 1.4 : 1.0 : 0.4, and fraction of energy going into OH product vibration as f ′ v ≫=0.23.

Theory of chromatography at finite concentration
Georges Guiochon,Laurent Jacob +1 more
TL;DR: In this article, the authors present a review of the theories published for finite concentration problems in the various fields of chromatography, and the basis of them all is shown to be derived from the same fundamental type of equations, which a mathematical method not already used in chromatography can solve.

Vibrational energy transfer in CH3I
Y. Langsam,S.M. Lee,A.M. Ronn +2 more
TL;DR: In this paper, the authors used the technique of laser induced infrared fluorescence to study energy transfer in the concluding member of this series, CH3I, and reported a single exponential decay rate of 23 ± 2 ms−1 torr−1.
