Abstract:We combine crossed-beam velocity map imaging with high-level ab initio/transition state theory modeling of the reaction
of S(3P) with 1,3-butadiene and isoprene under single collision
conditions. For the butadiene reaction, we detect both H and H2 loss from the initial adduct, and from reaction with isoprene,
we see both H loss and methyl loss. Theoretical calculations confirm
these arise following intersystem crossing to the singlet surface
forming long-lived intermediates. For the butadiene reaction, these
