The photodissociation dynamics of jet-cooled methyl thionitrite (CH3SNO) have been studied using 355 nm polarised laser photolysis and probing of the NO photofragment by polarised laser-induced fluorescence. The alignment A0(2) between the electronic transition dipole moment involved in the absorption of the parent molecule and the rotational angular momentum J of the nascent NO (v?=0 and v?=1) photofragment has been measured as a function of J up to J=44.5. The A0(2) values found are negative and approach the high-J limit confirming that the S2?S0 continuum transition of CH3SNO in the near-UV arises from a p*?p transition to a repulsive excited state.
