Phenyllithium was labeled with 6Li and I3C at the ipso carbon atom, and the tetramer was measured by solid-state NMR. The chemical shift tensor data were obtained by a moment analysis of the spinning side bands and were compared with the results obtained by calculations with the IGLO method. Althoug

## Abstract Upfield substituentβinduced ^13^C chemical shifts for aryl carbons of polymethyl substituted benzenes, phenols, anilines and thiophenols were investigated as a function of the proximity between substituents X and CH~3~ (X = CH~3~, NH~2~, OH and SH). The results indicate that the induced
## Abstract Carbonβ13 chemical shifts of fourteen __para__βsubstituted benzylbenzenes have been determined. The relative substituent chemical shifts (SCS) of the methylene carbons and the aromatic ring carbons (Cβ4, Cβ1β² and Cβ4β²) correlated well with the Hammett substituent effects using the dual
