Elektronenspektrum und Basizität des Cycl[3.2.2]azins

From theoretical predictions based on MO models together with the experimental polarization directions, the first four absorption bands of the UV. spectrum of cycl[3.2.2]azin ( I ) have been assigned to the following electronic transitions (in order of increasing energy): a) 1 A → 1 L b , (B 2 ); b) 1 A → 1 L a , (A 1 ); c) 1 A → 1 B a , (A 1 ); d) 1 A → 1 B b , (B 2 .
