Abstract
The ultraviolet spectrum of dibenzene chromium vapor has been observed under medium resolution conditions. At least three separate band systems are found, at least two of which display progressions of the totally symmetric vibration frequencies. Possible assignments are considered and compared with alternative level structures. It is concluded that the 3de2u level probably lies below the metal a1g orbital, and that term splitting may play a considerable role in determining the order of the excited states.Keywords
