bending transitions in the argon:hydrogen-iodide dimer have been analyzed following observation using a frequency and phase stabilized co-axially configured submillimetre supersonic jet spectrometer. This transition is from the ground state Ar-IH isomer to the excited state Ar-HI isomer. Molecular constants with one standard deviation to the fit are determined to be for the ground state: BJ = 1034.08372 (25) MHz, DJ = 10.5962 (77) kHz, HJ = -1.678 (69) Hz, aa = -1114.4014 (12) MHz, Daa = 82.3 (12) kHz. The corresponding constants for the newly determined upper state are: 0 = 263128.0649 (14) MHz, B J = 876.47909 (21) MHz, DJ = 5.3692 (52) kHz, H J = 1.669 (38) Hz, aa = -535.421 (10) MHz, D aa = -106.2 (11) kHz. This data is used to test the accuracy of currently available ab initio and morphed potentials for the complex and to propose refinement of the latter potential.
