✦ Synopsis

We present a kinetic study of the collisional removal of atomic germanium, Ge(4 3P1), with a range of olefins. This atomic state was generated by the repetitive pulsed irradiation of Ge(CH& in the presence of excess helium buffer gas in a slow flow system, kinetically equivalent to a static system, and monitored in the time-resolved mode, on time scales by which Boltzmann equilibration within Ge(4 3PJ) had taken place, at X = 259.3 nm (Ge( 5s( 3P1)) * Ge( 4p2( 3P 1))). A new body of absolute second-order rate constants, hR, for collisional removal by the olefins, R, are reported (2" = 300 K, errors = 20): R kR (X1O-1o cm3 molecule-' s-l) Ethylene Propylene cis-Butene 1-Pentene l-Hexene Cyclohexene Cycloheptene 1 ,&Cyclo-octadiene 1.
