Abstract

The presence of magnetic splitting in a line of MgH (first discovered by Wöhl) is confirmed by photo-electric observations. The umbral magnetic field deduced from the line splitting was 3150 ± 200 G against 2360 ± 200 G given by FeI λ5250. This difference is opposite in sign to that found by Wöhl. Lines from the B 2 X 2 transition of CaH are also shown to be broadened by Zeeman splitting.
