Effects of NH3 on 13C-Selective Infrared Multiple Photon Decomposition of CF2HCl by a CO2 Laser

Article abstract of DOI:10.1246/bcsj.60.4217

The effects of NH3 on product yields and 13C enrichment factors have been examined for the IRMPD of CF2HCl using a CO2 TEA laser.The IRMPD of neat CF2HCl yields only C2F4 and HCl as final products.The addition of NH3 resulted in the formation of CF3H and NH4Cl in addition to C2F4, and enhanced significantly the decomposition of CF2HCl.The enrichment factors of 13C in C2F4 and CF3H decreased with increasing NH3, but the decreases were relatively small.The mechanism of the IRMPD in the presence of NH3 is discussed on the basis of the observed results.
