Selective-absorption cross section of CF(3)CHCl(2) and CF(3)CDCl(2) at 10.2 and 10.6 microm of a TEA CO(2) laser.
A selective absorption cross section of 100:1 was measured for Freon 123-d and natural Freon 123 at the 10.2- and 10.6-microm lines of a TEA CO(2) laser. Multiple-photon absorption occurs at low fluence (0.1 J/cm(2)) at 10.2microm but not at 10.6 microm.
