Rotational transition frequencies of ArD+ were measured with an accuracy of a few hundred kilohertz in the 0.95-4.7 THz region, using a tunable far-infrared radiation source. Effective rotational parameters B, D, and H were determined for the ground vibrational state. The observed frequencies were combined with the previous data on all isotopic species of protonated argon ion to improve the mass-independent Dunham parameters Ukl, ΑArkl, and ΔHkl.
