N2  - Well-known theories of the profile and intensity of spectral lines are fist extended to lines involving a number of degenerate substates and under conditions where thermodynamic equilibrium does not apply. It is shown that much information can be obtained from an effective temperature and the absorption coefficient, and these two properties are then tabulated for the L&#945;, L&#946;, and H&#945; lines of hydrogen. The physical conditions considered cover electron concentrations from 108 to 1013 per cc., gas temperatures from 7.5 x 103 to 1.0X 106 °K., and incident black-body radiation (5000 °K.) diluted by a factor 1, 0.5, or 0.
