LIGHT ABSORPTION STUDIES: PART VI. THE EFFECTIVE INTERFERENCE VALUES OF NON-BONDED ATOMS IN SOLUTION. PART I. SOME PRELIMINARY OBSERVATIONS

Abstract

The application of light absorption data to determine minimum interference radii of various atoms in solution is examined. Three separate methods are suggested and the relation between potential energy and interatomic distance of two non-bonded atoms is discussed. The values obtained in neutral solution are as follows: H, 0.95 ± 0.1 Å; O (in C=O), 1.0 ± 0.15 Å; and CH3, 1.7 ± 0.2 Å.
