Photodissociation of chlorine isocyanate

Article abstract of DOI:10.1063/1.448962

Gaseous ClNCO exhibits a continuous ultraviolet absorption feature peaked near 250 nm.Photolysis of this compound at 249 nm produces bright blue emission identified as the A²Σ⁺ -> X²Π transition in NCO.The excited NCO arises from a collisional process in which N(²D) atoms, produced directly by the photodissociation, react with the parent ClNCO.The rate constant for this process is k = (2.1 +/- 0.2)*10^-11 cm³ s^-1. From production of N(²D) by the 249 nm photolysis, the heat of formation of gaseous ClNCO is inferred to be ΔH_f(ClNCO) >= 52.9 kcal mol^-1. ClNCO is metastable with respect to the ground electronic states of NCl and CO by 8.2 kcal mol^-1.
