Infrared matrix isolation studies on the t-butyl radical

Abstract
The infrared spectrum of the t‐butyl radical isolated in an argon matrix was obtained by gas phase pyrolysis of azoisobutane and 2‐nitrosoisobutane. The infrared spectrum is consistent with a C3v structure for the radical. The data obtained from the matrix isolation studies were used to reassess the ΔH°f,300 for the radical.
