## Abstract ^15^N chemical shifts in an extensive series of __para__ (15) and __meta__ (15) as well as __ortho__ (8) substituted benzonitriles, XC~6~H~4~CN, were measured in deuteriochloroform solutions, using three different methods of referencing. The standard error of the average chemical shif
Substituent chemical shifts (measured at natural abundance at 0 . 4 ~ concentration) and calculated (ab initio, STO-3G) electron densities at the nitrogen and oxygen (or sulphur) are reported for series of paraand rneta-substituted benzamides and thiobenzamides with NMe,, NH,, OMe, NJ3COMe, F, C1, B
Rotational barriers about the CÈN bonds of several N-acyl-N-methyl-a-amino acids and their esters R3COÈ N(R4)ÈCR1R2ÈCOOR5, and also N-Boc-protected dipeptides, were determined and the steric e †ects caused by the substituents R1-R5 are discussed by comparing them with the results of MM3 calculations
