Infrared spectra of the isobutyl and neopentyl radicals. Characteristic spectra of primary, secondary, and tertiary alkyl radicals
Abstract
Infrared spectra are presented for the isobutyl and neopentyl radicals for the first time. Significant differences are observed in the β-CH stretching and pyramidal bending regions between primary alkyl radicals with straight chains and those with branched chains like the isobutyl and neopentyl radicals. These are compared with spectra of other alkyl radicals to establish characteristic infrared spectra of primary, secondary, and tertiary alkyl radicals. © 1981 American Chemical Society.
