A back-propagation artificial neural net has been trained to estimate
C-13 chemical shifts from the results of AM1 and PM3 semiempirical MO
calculations. The input descriptors include the atom-centered monopole,
dipole and quadrupole moments derived from the natural atomic
orbital/point charge (NAO/PC) model, the four highest bond orders to the
carbon atom being considered and the elements to which these bonds are
made. The resulting net estimates the chemical shifts of a test set of
156 chemical shifts with a standard deviation of less than 7 ppm from
the experimental values for AMI and slightly more for PM3.
