Abstract : The dependence of the positions of both the red and the violet satellite bands of alkali lines on the nature of alkalis was investigated from the microphotometer traces of over 100 satellites of the absorption lines of Li, Na, K, Rb and Cs in the presence of He, Ne, Ar, Kr, and Xe. It was found that for a given foreign gas, the absolute magnitudes of satellite-line separation for both red and violet satellites decreased with increasing atomic weights of the alkalis; while for a given alkali, the line separation increased with the atomic weights of the foreign (perturbing) gas for red satellites but decreased for violet satellites. Red satellites were observable only for heavy gases (Kr and Xe). The red satellite separation had a peak value for the third member of Li and for the second member of other alkali absorption series. Violet satellite separations were very large for the resonance lines but decreased so rapidly for the higher members that no satellites were resolved for the second or higher members of the principal series for the heavy gases (Kr and Xe). For a given foreign gas, the red satellite separation for the long wave length component (2)P1/2) of the doublet decreased, while that for the short wavelength component ((2)P3/2) increased with the atomic weight of the alkalis.
