Abstract: We have observed in absorption 14 rotational transitions in the first excited vibrational state of H 35Cl and H 37Cl. A tunable FIR spectrometer was used with a multiple-pass cell to improve the sensitivity. Transitions with J? ranging from 2 to 8 were recorded, with Doppler resolution, in the region between 1.8 and 5.5 THz and their frequencies were measured with an average accuracy of several parts in 108. These transitions were analysed together with high J rotational transitions previously measured in emission in the infrared on the basis of an effective Hamiltonian, which includes terms up to the eighth power in the angular momentum.
