Abstract

At frequencies close to that of a spectral line, a gaseous medium shows not only a rapid variation with frequency of absorption coefficient but also of refractive index. This anomalous dispersion is particularly important in the analysis of lines formed in the presence of a magnetic field. The differently split components of the line have different dispersions which leads to a rotation of the axes of the polarization ellipse as the radiation traverses the medium.
