We describe in this paper a simple interferometric technique which allows a direct and simultaneous determination of energy absorption and of the vibrational-translational relaxation time of polyatomic molecules strongly excited by reasonant,infrared (10.6 μm) laser radiation. In particular,we have applied this method to the study of freon-22 (CF2HCl),a medium-size molecule that,apart from its potential application in13C isotope separation,shows interesting absorption features in the 10 μm region. The results are also compared with our previous findings in SF6.
