Abstract

Infrared multiple-photon dissociation of many fluorinated and chlorinated deuterium-containing hydrocarbons has been thoroughly investigated with a view to attaining high isotopic enrichment. Among these molecules little attention has been paid to chloroform, although it has a high rate of H/D exchange in base-catalyzed aqueous solutions, probably because the CDCl₃ v4 mode (913 cm⁻¹) is resonant with the low gain 10.96-μm P(50) line of the CO₂ laser.
