Carbon-13 chemical shifts are reported for 16 para-substituted phenyl isothiocyanates measured at 1 and 1Omol 9'0 in chloroform-d solution. Data for the -N=C==S group were not obtained at lmol 9'0, but concentration effects for the other resonances were negligible. Hammett, dual substituent paramete

Linear free energy relationships (LFER) were applied to the 1 H and 13 C NMR chemical shifts (d N , NZ 1 H and 13 C, respectively) in the unsaturated backbone of cross-conjugated trienes 3-methylene-2-substituted-1,4-pentadienes. The NMR data were correlated using five different LFER models, based o
## Abstract All carbon‐13 chemical shifts for 11 __para__‐substituted __N__,__N__‐dimethylbenzamides in 1 mole % chloroform solution are reported, with assignments based upon double resonance experiments, analogy to chemical shifts of benzamide, and self‐consistency between experimental and calcula
