摘要：
The spectral and luminescent properties and the photolysis of a neutral form of the isolated molecule of methyl[(4-aminophenyl)sulfonyl]carbamate (asulam) are interpreted with the aid of methods of quantum chemistry using the theory of intramolecular photophysical processes. It is shown that the breaking of the C-S bond in the molecule occurs according to the predissociation mechanism and is most efficient in the state T(pisigma(CS)*). The photoinduced breaking of the N-S bond occurs according to the same mechanism and is most efficient in the state S(npi(NS)). (C) 2004 MAIK "Nauka/Interperiodica".
