摘要:
AbstractThe ionization potentials of methyl‐,t‐butyl‐ and trimethylsilyl‐substituted pyridines have been determined by high‐resolution photoelectron spectroscopy. The results are discussed in terms of destabilizing inductive and stabilizing conjugative effects of the substituents, and have been parametrized on the basis of a HMO‐type perturbation treatment. Our data are in accord with the idea that the topmost occupied orbital in pyridine is a ‘lone

摘要:
AbstractThe photocelectron spectra of nortricyclene (=tricyclo[2.2.1.02,6]heptane) and of triasterane (=tetracyclo[3.3.1.02,8.04,6]nonane) have been recorded and a tentative assignment of the bands has been put forward on the basis of MINDO/2 SCF calculations.
