Abstract:The effects of the cation—molecule interaction on the i.r. and Raman intensity of the CN stretching band in hydrogen cyanide are investigated. It follows from the calculated data that the cation—molecule interaction increases about 10 times the i.r. intensity of the CN stretching band, while the corresponding Raman intensity is slightly decreased. The present theoretical data for HCN and HCN … Li+ are utilized for the interpretation of the observed spectroscopic regularities in the i.r. Raman spectra of acetonitrile solutions of electrolytes.
