Vibrational Line Profiles as a Probe of Molecular Interactions
Michael S. Bradley and Cheryl Bratu
Department of Chemistry, Valparaiso University, Valparaiso, IN 46383
Cover
May 1997
Vol. 74 No. 5
p. 553
Abstract
A Raman experiment which yields basic insights into molecular interactions via vibrational line shape analysis is presented. Specifically, line shifts and changes in profile of the acetone C-C and C=O vibrations during dilution with methanol and CCl4 are examined. The spectra during methanol dilution reveal an increase in attractive interactions, while those resulting from dilution with CCl4 reveal increasing repulsive interactions.
