Conclusions
-
1.
The photoelectron spectra of seven methyl-substituted 1,3-dioxanes have been recorded and identified.
-
2.
Empirical parameters have been found which characterize the magnitude of the inductive effect and the hyperconjugation between theσ C-C bonds of the substituents and the ne − and na + orbitals.
-
3.
INDO quantum mechanical calculations have been carried out on the investigated compounds and qualitatively reproduce the pattern of the changes in the ionization potentials in the spectra.
