초록/요약
The competitive photodissociation kinetics of the isobutanal radical cation ((CH3)2CHCHO+, 1) were investigated using experimental and theoretical methods. The photodissociation was followed by the 2 + 1 REMPI process in the gas phase. The reaction pathways for the main product ions with m/z 43 and 29 were determined by calculating the potential energy surface of the dissociation with the G4 method. Through a kinetic analysis using RRKM calculations, we proposed that the main photodissociation pathways were 1 → (CH3)2CH+ + CHO, 1 → (CH3)2CH+ + H + CO, and 1 → CH3CH2COCH3 + → CH3CH2 + + CH3 + CO. © 2017 The Royal Society of Chemistry.
