Abstract
The McWeeny theory has been used to calculate the shielding parameters for polycyclic hydrocarbons up through four rings. These results are presented along with experimental values, some of which come from new analyses of 100‐Mc/sec NMR spectra of these compounds, and semiquantitative agreement is observed. The Jonathan—Gordon—Dailey semiempirical equation for spin—spin coupling constants is also subjected to further test by new data. Absence of inter‐ring spin—spin coupling is reconfirmed.Keywords
