Aromatic solvent induced shifts in molecules with and without a permanent electric dipole moment
Abstract
It is shown that there is little justification for regarding aromatic solvent induced shifts as being of a ‘chemical’ origin. A literature method of determining the direction of molecular dipole moments is criticised. Data are presented for molecules which have no net dipole moment, and for some which do; the latter are analysed in terms of the approach of Laszlo and Engler.
