Spectral characteristics of several simple substituted B,B‐bis(mesityl)pyrroloboranes are reported which support a theoretical treatment by Bonacic‐Koutecky and Michl ( J. Am. Chem. Soc. 107 , 1765 (1985)) describing the excited states of simple aminoboranes as an example of twisted internal charge transfer. In the aminoboranes the pyrrolo moiety functions as the electron donor group and the empty p ‐orbital of the boron atom as the acceptor.
