英文摘要: Photodissociation dynamics of C4H2 at 164.41 nm through the Rydberg state R((1)Sigma(u)) have been studied using the high-resolution H atom Rydberg tagging technique. Experimental evidences show that two different predissociation pathways exist to form the ground C4H (X-2 Sigma(+)) and electronically excited C4H (A(2)Pi) products: the former has statistical and isotropic translational energy distribution through internal conversion (IC) to the ground state, while the latter has non-statistical and anisotropic translational energy distribution through IC to the excited repulsive state. The vibrational progressions of C4H (A(2)Pi) products have also been observed and assigned. (C) 2013 AIP Publishing LLC.
