Abstract: Atmospheric-pressure argon plasma jet is generated with syringe needle-ring electrodes in an 8 kHz sinusoidal excitation voltage. It is found that the rotational temperature of nitrogen is in the range of 333 - 373 K obtained by comparing the simulated spectrum with the measured spectrum at the C-3 Pi(u) -> B-3 Pi(g) (Delta nu = -2) band transition, the electronic excitation temperature is in the range of 3187 - 3243 K determined by the Boltzmann's plot method, and the oxygen atomic density is in the order of magnitude of 10(16) cm(-3) estimated by the actinometry method, respectively.
