propene dissociation channels were characterized by ab initio ccsd(t)/6-311++g(d,p) calculations. inthis work the detailed mechanism of propene dissociation to c2h4+ch2, c2h2+h+ch3, c2h2+ch4 andc3h3+h2+h have been investigated. according to our calculations, ten fragments can be classified intofive dissociated channels. our results point out that two mechanisms come into play in the h2 eliminat...
