Conformation Degenerate ground state

The two molecules that have one- or three-electron n bonds show triplet ground states. This conforms to Hund s rule in atoms where one has unpaired electrons distributed among degenerate orbitals to produce the highest possible multiplicity. The other molecules all have electron pair bonds or unshared pairs and are in singlet states. [Pg.161]

The expectation that the 19-mer, which can form a perfect shape without any holes ( 6-7-6 stmcture), is a prototype of peculiar behavior is, however, wrong. This is due to the existence of degenerate less symmetric ground-state conformations [as the exemplary conformation shown in Fig. 5.6(c)]. [Pg.144]
