Abstract
Abstract Photodissociation pathways for 3,4-dichloro-1,2,5-thiadiazole was investigated in its ground state at various wavelengths in the UV region. The photolysis products were identified by the UV absorption and emission spectroscopy. Molecular chlorine (Cl 2 ) elimination was observed using absorption methods in the UV region. UV absorption and quantum calculation confirms the migration of chlorine atom and subsequent ring opening to form NC C(Cl 2 ) N S isomer. Multiphotonic excitation leading to the UV emission in the vicinity of 389 nm was observed due to the formation of CN(B 2 Σ + ) moiety. New UV absorption bands observed at ∼255 and ∼290 nm were assigned to the its isomer NC C(Cl 2 ) N S.
