Popis: Ab initio calculations at the UMP2/cc-pVTZ level were used to determine the stationary points of fluoroformyloxyl (FCO 2 (C 2V )) with atomic hydrogen reaction on both singlet and triplet potential energy surfaces. One intersystem crossing has been found between triplet and singlet potential energy surfaces. Calculations reveal that the FCO 2 (C 2V ) + H reaction can progress on both singlet and triplet potential energy surfaces by the attack of atomic hydrogen to O–atom of FCO 2 (C 2V ) molecule to form the main products of OH + FCO and HF + CO 2 . The intersystem crossing has a negligible role in the reaction mechanism of FCO 2 (C 2V ) + H.
