Anomalous Magnetic Rotation in Excited Neon

The anomalous magnetic rotation of the plane of polarization was observed near twenty lines belonging to the transition, $s_3-p_k$, $s_4-p_k$, and $s_5-p_k$. Quantitative measurements were made of the angle of rotation for different frequencies near sixteen lines. The effect is the normal effect, symmetrical on both sides of the line, the direction of rotation being negative.
