The potential energy surface for the thermal isomerization of fulvene to benzene was studied by modified Gaussian-2 (G2M) and the bond additivity-corrected fourth-order perturbation Mgller-Plesset (BAC-MP4) methods. Three isomerization pathways were investigated. One involves the intermediate preful

β¦ Synopsis
Hartree-Fock and many-body perturbation theoretical calculations are used to determine the geometries and energies of NCCN (l), CNCN (2), and CNNC (3) as well as the transition state structures for interconversion among these three isomeric species. It is found that there is a reaction path with a relatively low (0.66 eV) barrier for conversion of 3 to 1, consistent with the thermal instability of 3.

Ab initio molecular orbital calculations have been used to determine the structure of protonated ozone. Four stable minima were found on the 03H+ singlet potential energy surface. Three forms correspond to ozone protonated at the central oxygen ((22") or at the terminal oxygen (two C, isomers, E and
Mixtures of cyanogen and nitrous oxide diluted in argon were shock-heated to measure the rate constants of ( 2 ) and the spectral coincidence of a CO infrared absorption line [v(2 +-l), J(37 +-38)] with a CO laser line [v(6 + 5 ) , J(15 + 16)l was exploited to monitor CO in absorption. The CO measu
The mechanism of isomerization of allyl thiocyanate to allyl isothiocyanate has been investigated both experimentally and theoretically. The kinetic study indicates that the reaction is unimolecular and is not ionic. The entropy of activation suggests strongly that the mechanism involves a cyclic tr
