Infrared diode laser kinetic spectroscopy has been employed for measurement of the decay of ArD+ ions. The lifetime of ArD+ increases with increasing buffer gas pressure from 20 us to 100 us in a cylindrical (radius 7.5 mm and 10.5 mm) glow discharge plasma and, from 200 to 600 us in a hollow cathode (radius 20 mm) discharge plasma. The changes in ArD+ lifetime range from 7.9 us/torr to 92 us/torr and depend on the type of buffer gas (Ne, He, Ar) and cell radius. The unusual kinetics of ArD+ is controlled by ambipolar diffusion and by the ion mobilities.
