## Dedicated to Professor Emanuel Vogel A recent computational study of Schleyer and co-workers [1] is reviewed, which led these authors to the firm conclusion that [18]annulene has a localized structure with alternating single and double C,C bonds, contrary to earlier crystallographic analyses of
IN 1947 Plattner and collaborators 1,\*,3 isolated two new antimycobacterial substances, enniatin A (C24HWN206, m.p. 121-122', [a]? -92', c 1 in CHC13) and enniatin B (C22H38N206, m.p. 173-175', [a], 2o -108', c 0.6 in CHCl 3
Ab initio molecular calculations carried out at the UQCISD (T ) /6-3 1 1 + + G ( 3df, 2p) and RCCSD (T ) /cc-pVTZ levels have been used to re-examine the heats of formation of the [C, Hs, N] +' radical cations and related species. The following values have been obtained: AH&s8 (H&NH) +' = 1046+ 10 k
