Abstract
Fragment ion-photon coincidence (FIPCO) spectra by 120 eVelectron impact on trifluoromethane (CHF3) have beenobserved, in which optical emission in the 200-600 nm regionhas been detected. The CF3+, CHF2+,CF2+ and CF+ ions were observed in the FIPCOspectra. The kinetic energy distributions of these ions wereestimated on the basis of the Monte Carlo simulation of theirobserved band shapes. Considering the total kinetic energyrelease in the dissociation processes producing CF3+and CHF2+, we have concluded that the production ofCF3+ and CHF2+ follows the D-B and D-C emissions of the parent ion, respectively. The CF2+and CF+ ions were correlated with the Balmer emissionfrom the excited hydrogen atom. These dissociation processesproducing CF2+ and CF+ take place after theexcitation to singly charged superexcited states of CHF3.
