Electron density in functional groups of free radicals determined by infrared spectroscopy
Abstract
Stretching frequencies in the i.r. spectra of several diarylketyl and tetracyanoethylene anion radicals have been compared with the frequencies of the unreduced molecules. Some correlation of known electron densities (from e.s.r. results) and observed stretching frequencies has been attempted. Correlation equations developed apply best for ketyls and tetracyanoethylene.
