The effects of NH<SUB>3</SUB> on product yields and <SUP>13</SUP>C enrichment factors have been examined for the IRMPD of CF<SUB>2</SUB>HCl using a CO<SUB>2</SUB> TEA laser. The IRMPD of neat CF<SUB>2</SUB>HCl yields only C<SUB>2</SUB>F<SUB>4</SUB> and HCl as final products. The addition of NH<SUB>3</SUB> resulted in the formation of CF<SUB>3</SUB>H and NH<SUB>4</SUB>Cl in addition to C<SUB>2</SUB>F<SUB>4</SUB>, and enhanced significantly the decomposition of CF<SUB>2</SUB>HCl. The enrichment factors of <SUP>13</SUP>C in C<SUB>2</SUB>F<SUB>4</SUB> and CF<SUB>3</SUB>H decreased with increasing NH<SUB>3</SUB>, but the decreases were relatively small. The mechanism of the IRMPD in the presence of NH<SUB>3</SUB> is discussed on the basis of the observed results.
