Abstract
Two level systems can interact coherently with infrared laser radiation giving rise to Rabi oscillations. The description of the interaction can in most cases, be cast in terms of the optical Bloch equations, as was shown by Feynmann et al.' Experimentally the interaction may be displayed using apparatus such as that described in reference 2. A molecular beam is generated from a supersonic expansion, crosses the output of a frequency stabilised carbon dioxide laser and impinges on a 2K bolometer. A Stark field is used to tune vibrational transitions of the beam molecules into resonance with the laser: the degree of vibrational excitation can be measured by monitoring the change in resistance of the bolometer as the molecules are tuned through resonance.
