## Abstract The chemical shifts of the aldehydic proton in furfural, thiophenealdehyde and benzaldehyde have been measured in fourteen solvents. The correlation of the chemical shifts of thiophenealdehyde and benzaldehyde is excellent (__r__ = 0·996) while it is lower for furfural–benzaldehyde (__r
The protonation of acetylene and ethylene (yielding the vinyl aqueous basicities afforded the hydration energies of the protonated bases. It was found that the aqueous protonation of and ethyl cation, respectively) was investigated computationally by ab initio calculations [B3LYP/6-31G(d,p)], in the
## Abstract Sum‐over‐states perturbation and finite perturbation calculations, within the ‘Solvaton’ model, are presented for the variation of some ^17^O and ^19^F chemical shifts as a function of the dielectric constant of the medium. In general, the nuclear screening and charge are predicted to i
The methylene protons of dibenzyl sulphoxide are magnetically equivalent in low dielectric and non-equivalent in high dielectric constant solvents, while for diphenacyl sulphoxide this behaviour is reversed. In both cases, the variation in the magnitude of the non-equivalence reflects a greater down
