Proximity effects on the nuclear magnetic shielding tensor. Part 1. An ab initio study of 17O and 19F chemical shifts in the proximity of a methyl group
The deshielding effect produced by repulsive interactions between proximate groups was studied from a theoretical point of view, calculating the magnetic shielding constants for the following nuclei: 17O in di-coordinated and carbonyl oxygen atoms; 19F and 13C. The "super molecule" approac...
