Nitrogen and nitrogen - argon gas mixtures were excited by 1.5 NeV protons from a Van De Graaff generator. Intensity measurements were made for the first negative lambda 3914.4A and the second positive lambda 3371.3A transitions of molecular nitrogen. A determination of the excitation coefficient C, which is a function of the reaction rate coefficient and excitation cross section, was made for the nitrogen first negative and second positive transitions. The excitation coefficient C is a constant for each transition and contains all non-radiative energy transfer constants of the general rate equation. For the first negative transition the value of excitation coefficient was found to be .256 plus of minus .046 and for the second positive transition it was found to be 2.25 plus or minus .12. Author
