✦ Synopsis

We present crossed-beam scattering results for reaction of ground state O( 3 P) and electronically excited O( 1 D) with n-pentane at a collision energy of 13 kcal/mol. The results were obtained using velocity map imaging with 157 nm singlephoton ionization of the products. Using this probe, the only reaction channel observed was that producing the hydrocarbon radical and OH. The results show dramatically contrasting dynamics, with backward-sideways scattering dominating the ground state triplet reaction and isotropic/forward scattering for the singlet reaction.
