Abstract
FOLLOWING on previous work in which we observed the spectrum of nickel hydride1, NiH, in a high-tension arc between nickel electrodes in a flame of hydrogen burning in air, we have made similar experiments with other metals. With manganese, four bands with open rotational structure have been observed. The strongest band is in the yellow-green; it is degraded to the violet, and shows a rather complicated rotational structure; there is a strong head at 5678, and a fainter one at 5722. Bands in the green (heads at 5172 and 5205) and red (head at 6240) have a rather similar appearance, and the three bands may be considered tentatively as the (1,0), (0,0) and (0,1) bands of the same system. There is also a band in the blue; this is degraded to the red and has a simpler rotational structure than the other bands; its head is at about 4500 A.
