The rotational spectra of H235Cl+, H237Cl+ and HD35Cl+were measured in the 180-550 GHz region using a source-modulated submillimeter-wave spectrometer. The ions were generated in a free space absorption cell by a hollow-cathode discharge in a gas mixture of H2 (D2) and Cl2 Precise rotational constants including the electric quadrupole coupling constants were determined for the three species. The centrifugal distortion constants were used to derive the harmonic force field of H2Cl+, which was then applied to calculate the zero point average structure of the ion: r2=1.32091±0.00015 Å and θz =94.228±0.023º, where errors are due to residual inertial defects of the corrected moments of inertia.
