Abstract

The CF3Br molecule is the heaviest molecule which has been optically pumped by a CO2 laser in CW operation (Knight, 1980). Due 79 to its molecular weight (m = 148 a.m.u for the CF 3 79 Br isotope), it presents the main following features: i) an infrared absorption spectrum of very high density, ii) an infrared Doppler absorption linewidth less than 40 MHz, iii) rotational transitions at long wavelengths (λ ≥ 1 mm).
