Configuration interaction calculations of the excited states of polyenes C H N N+2(N=4r 6,8, 10 and 12) and (Si), (m=3-7) segments have been performed within the framework of the Pariser-Parr-Pople approximation. Characteristics of the higher twophoton state, n 'Ap in these oligomers are discussed b
can be exchanged with D,O. Thus, two insertions of two adamantylidenes into two different 0 -H bonds of fl-CD have taken place. The absolute amount of OH insertion products 4 B-CD and 5 . 8-CD detected by FAB mass spectrometry (Scheme 1 ) is not yet known. Since these compounds could not be found by
