Observations of the polarization of the D line resonance radiation of sodium indicate that the transition probabilities for the various components of the Zeeman pattern are substantially in agreement with the predictions of the so-called sum rule. Observations in relatively strong fields show the effect of non-uniform distribution of intensity in the exciting spectral line. The assumption that the distribution of energy in the exciting line is due practically entirely to Doppler effect leads to equations for the variation of polarization with field strength which are well verified experimentally. Any broadening of the line by collision or by a coupling effect is evidently quite small in comparison with the Doppler breadth.
