Abstract
The ultraviolet spectrum of methyl isothiocyanate (C[H.sub.3]NCS) and the quantum yield for its dissociation into methyl isocyanide (C[H.sub.3]NC) and atomic sulfur at 308 nanometers, φ = 0.98 ± 0.24, were meaasured. Methyl isothiocyanate is widely used as an agricultural fumigant and readily eoters the atmosphere during and after application. Th, results indicate that photodissociation by sunlight is an effectiv, pathway for its removal from the atmosphere.
Methyl isothiocyanate (C[H.sub.3]NCS, MITC) is widely used in agriculture as a soil fumigant; it is a toxic substance that irritates the skin and mucous membranes (1). In 1991, 2.1 x [...]
