A study of the vacuum pyrolysis of 11 -oxatricyclo[6.2.1.02,7]undeca-2,9-diene. The HeI ultraviolet photoelectron spectrum of 1,2-cyclohexadiene

Abstract

A newly developed ultraviolet photoelectron spectrometer – CO 2 , laser apparatus that utilizes a 50-watt CW CO 2 , laser as a directed heat source is used to study the vacuum pyrolysis of 11-oxatricyclo[6.2.1.0 2,7 ]undeca-2,9-diene (4). We report the HeI photoelectron spectrum of the strained cyclic allene 1,2-cyclohexadiene (1) that correlates with the HAM/3 ionization energies calculated with the optimized C 2 , equilibrium structure …
