## Abstract Carbon‐13 chemical shifts of sixteen monosubstituted ethylenes were obtained. In order to explain the chemical shifts, σ and π electron densities of these compounds are calculated by the σ‐included ω‐HMO method.See Ref. 8. A linear relationship exists between carbon‐13 chemical shifts

## Abstract C‐13 and F‐19 NMR spectra of seventeen __para__‐substituted fluorobenzenes were measured and the chemical shifts as well as coupling constants with respect to substituents were analysed. The chemical shifts of the fluorine, the C~1~ and the C~2~ atoms were found to depend on the total e
