The Zeeman effect for the arc spectrum of rhodium has been photographed with a large Bitter type magnet at field intensities up to 94,000 gauss. Data are given on the Zeeman patterns of 446 lines, from which g values are calculated for nearly all the known low and middle spectral terms of the rhodium atom. For terms arising from the low even configuration, the g values are found to be given by LS coupling formulas, except for the terms having or , in which case a perturbation between the overlapping d9 and d85s configurations destroys the agreement. The g sum rule is found to be valid when the terms from the two configurations are taken together. For the odd configurations the g values lie between those predicted by LS and Jj coupling formulas. The classification of lines by other investigators has been thoroughly checked, and a new term list is given with 14 additional terms. The old term values have been recalculated on the basis of new wave-length data.
