中文摘要	product pair correlation in ch3oh photodissociation at 157 nm: the oh + ch3 channel
英文摘要	the oh + ch3 product channel for the photodissociation of ch3oh at 157 nm was investigated using the velocity map imaging technique with the detection of ch3 radical products via (2 + 1) resonance-enhanced multiphoton ionization (rempi). images were measured for the ch3 formed in the ground and excited states (nu(2) = 0, 1, 2, and 3) of the umbrella vibrational mode and correlated oh vibrational state distributions were also determined. we find that the vibrational distribution of the oh fragment in the oh + ch3 channel is clearly inverted. anisotropic distributions for the ch3 (nu(2) = 0, 1, 2, and 3) products were also determined, which is indicative of a fast dissociation process for the c-o bond cleavage. a slower ch3 product channel was also observed, that is assigned to a two-step photodissociation process, in which the first step is the production of a ch3o(x e-2) radical via the cleavage of the o-h bond in ch3oh, followed by probe laser photodissociation of the nascent ch3o radicals yielding ch3(x (2)a(1), nu = 0) products.
