✦ Synopsis

The mixed gas (Ar + N,) plasma has been generated by a 6 KW, 10.3 MHz radio frequency oscillator. The flame got extinguished if N, exceeded more than 20% of Ar. The Boltzmann plot using spectral intensities of Ar I and NI lines in the wavelength range 4000-4510 A have been used to determine the excitation temperature. The results show that excitation equilibrium between two species exist since the temperatures are found to be nearly same for both species.
