Аннотация:Pure rotational transitions of molecular hydrogen were studied by means of time-domain coherent anti-Stokes Raman spectroscopy (time-domain CARS) in a wide pressure range from 26 down to 0.003 atm at room temperature. Dicke effect manifestation was observed for S0(0) and S0(1) transitions in the forward scattering geometry. The longest dephasing time T2 measured was 8.7 and 6.2 ns, corresponding to spectral line bandwidth 0.0012 and 0.0017 cm−1
