Nh. Werstiuk et al., A STUDY OF THE VACUUM PYROLYSIS OF 11-OXATRICYCLO[6.2.1.0(2,7)]UNDECA-2,9-DIENE - THE HEI ULTRAVIOLET PHOTOELECTRON-SPECTRUM OF 1,2-CYCLOHEXADIENE, Canadian journal of chemistry, 74(10), 1996, pp. 1903-1905
A newly developed ultraviolet photoelectron spectrometer-CO2 laser app
aratus that utilizes a 50-watt CW CO2 laser as a directed heat source
is used to study the vacuum pyrolysis of 11-oxatricyclo[6.2.1.0(2,7)]u
ndeca-2,9-diene (4), We report the HeI photoelectron spectrum of the s
trained cyclic allene 1,2-cyclohexadiene (1) that correlates with the
HAM/3 ionization energies calculated with the optimized C-2 equilibriu
m structure obtained with AM1 and the molecular orbital energies of th
e optimized C-2 equilibrium structure calculated at the ab initio HF/6
-31G* level of theory.
