Accurate wavelength measurements in the molecular nitrogen pulsed laser have been made. Four new ir laser bands were discovered. In addition, about two hundred new stimulated emission lines belonging to the first and second positive systems were obtained and identified as to rotational quantum number. An analysis of the possible pumping mechanisms in accordance with experimental results is given.
