Re. Jetton et al., THE PREDICTION OF THE C-13 NMR-SPECTRA OF ARENES USING MATHEMATICAL-MODELING TECHNIQUES, Journal of molecular structure. Theochem, 388, 1996, pp. 139-144
The prediction of the C-13 NMR spectra for derivatives of benzene has
been investigated using mathematical modeling techniques. A large data
set (n = 7440) was investigated and a number of models developed. The
most practical model contained 52 terms and had a correlation coeffic
ient of observed against predicted line positions of 0.99 with an aver
age error of prediction of 1.6 ppm.
