The fluorescence excitation spectra of CN(A,B → X) and CF3(2A′1 → 1A″2) and the quantum yield for the CN(B) radical formation were measured in the photodissociation of CF3CN in 105–135 nm. The quantum yield for the CN(B) radical formation was found to be only a few percent. The similarity in the excitation energy dependence of CN(B → X) and of CN(A → X) indicated a common dissociation mechanism via the 3s Rydberg state of CF3CN for both states.
