   In NMR, it is well-known that the chemical shift conveys structural informa­ tion, e. g. a carbonyl carbon will have a resonance frequency appreciably dif­ ferent from a methyl carbon, etc. The relation between structure and chemical shift is mostly established by empirical rules on the basis of …
