We have observed a new type of band series. The lines in these bands have been used previously for high resolution assignment $purposes.1,2$ The approximate frequency of one of the bands is given by the following equation: \nu\sim 2{C}({J}+\frac{1}{2})+\frac{1}{2}({A}+{B}). This new series has a spacing of approximately 2C and has the property that the frequency of a band center divided by the spacing is close to J + 1/2 + (A + B)/4C. This latter quantity is in general neither integral nor half-integral. In low resolution work it is normally observed to be one or the other. A discussion of these and other characteristics of this new band type and the information that can be obtained from it will be presented.
