 Title    Charge-Transfer Spectra of Some Heterocyclic Cations  
 Abstract    Energies of the first charge-transfer bands of complexes of heterocyclic pyridi-nium-like cations with various electron donors (the iodide ion, benzenoid h ydro­ carbons) yield linear correlations with the HMO energies of the lowest unoccupied rr-molecular orbitals (LUMO) o f the hetero­ cyclic acceptors. The experimental charge-transfer band maxima were taken from the literature. Charge-transfer band maxima for the complexes of the 2,4,6-trim ethylpyrylium cation with several electrons donors (diethyl-amine, N,N-dimethylaniline, pyridine N-oxide, anthracene) have been determined and compared with the analogous data for the tropylium cation.
