The infrared spectrum of isocyanic acid, HNCO, has been recorded in the range 8–80 cm−1 with a resolution of about 0.004 cm−1a-type and b-type rotational transitions have been measured and assigned in the ground state and in the ν4 = 1, ν5 = 1, ν6 = 1, and ν5 = 2 vibrational states.Improved values of the ground state rotational and centrifugal distortion constants in the Ir S-reduced Hamiltonian of Watson have been obtained in a simultaneous analysis of our measurements and microwave, millimetre-wave, and far infrared data reported previously. Sub-band origins and effective spectroscopic constants have been determined for each excited vibrational state. An accurate value for the ν6 band origin, at 656.287 cm−1, has been deduced.
