Collisional De-excitation Rates for the First Negative and Second Positive Systems of Nitrogen by Water Vapor

摘要

Nitrogen-water vapor mixtures were excited by 1.5 MeV protons from a Van De Graaff generator. Intensity versus pressure data were recorded and plotted for the first negative (B doublet Sigma(u)(+) to X doublet Sigma(g)(+)) transition (3914.4A), and second positive (C triplet Pi(u) to B triplet Pi(g)) transition (3371.3A) in nitrogen. Theoretical equations were derived for the relative intensity as a function of pressure. Using these equations in conjunction with experimental data, the reaction rates were determined. (Author)
