Abstract
AN investigation of certain spectral lines emitted in a high-voltage arc between brass electrodes in nitrogen gas was made under pressures of from 1/7 to 85 atmospheres. The arc was run in and out of a magnetic field of 4,000 gauss. An empirical relation between the shift with and without a magnetic field at varied pressures for nine spectral lines has been found. There was a certain amount of scatter in the shifts of the lines, but among the hundreds of measurements of the spectral lines studied from Eastman Kodak spectrum analysis No. 2 plates, a significant pattern of shifts was found which differed for emission in a magnetic field from emission in a nonmagnetic field.
