Abstract
MECKE and Guillery1 identified only four band heads given in Kayser's “Handbuch der Spectro-scopie” (6, 786, 1912) as due to the oxide of vanadium and assigned them their vibration quantum numbers. These are the (1,0), (0,0), (0,1) and (0,2) band heads. Prof. Ferguson2 has recently photographed the bands and measured thirty-one heads from low dispersion spectrograms between 4800 and 8700. The bands have now been photographed under high dispersion and more accurate data have been secured. The measurements have also been extended in the shorter wave-length region as far as 4500. The band-heads are double with a separation of about 2.8v between them. The equation of band head wave numbers remains, however, practically the same as that given by Prof. Ferguson.
