摘要: A method of gas temperature determination in nitrogen or doped discharges is presented. The employs fits numerically generated spectra the 0-0, 1-0, and 2-0 bands first positive system (B Π3g→A Σ3u+) to experimental measurements. Excellent agreement between values inferred by using this 3-0 band peak ratio [M. Simek S. De Benedictis, Plasma Chem. Proc. 15, 451 (1995)] demonstrated for a helicon plasma. spectral model available use plasma spectroscopy community. model, along with user instructions, can be downloaded from Electronic Physics Auxiliary Publication Service American Institute Physics. includes line positions, Honl-London factors, provides rapid if one more aforementioned emission rovibrational are available.
