This thesis describes a spectroscopic and theoretical investigation on the nature of the interaction between a carbonyl or sulfonyl group, and the pi orbitals of a phenyl or thiophene ring. The relation between the chemical shift of a carbon atom in the 13C-NMR spectrum and the charge density at that carbon atom was studied. ... Zie: Summary
