PHOTODISSOCIATION OF S2CL2 AT 308-NM BY TRANSLATIONAL SPECTROSCOPY

The photodissociation of S2Cl2 at 308 nm has been studied by the cross ed laser-molecular beam technique. Both the product translational ener gy distribution and the anisotropy parameter beta were derived from th e measured time-of-flight spectra. Results show that S2Cl2 undergoes a simple S-Cl bond scission with the fragments recoiling anisotropicall y. The averaged translational energy of the products is 88 kJ /mol. S2 Cl may produce two pairs of fragments, S2 + Cl and SCl + S, by absorbi ng an additional photon. These secondary dissociation processes were o bserved at high laser powers.
