## Abstract 2โFluorobenzamide and its __N__โmethyl derivative show spinโspin couplings between the aromatic fluorine and the nitrogen and carbon of the amide group, which are absent in the corresponding N,Nโdimethylamide. The __N__โmethyl compound, in which there is a hydrogen bond between the fluo
## Abstract The correlation between the puckering angle of the fourโmembered cycle and ^4^__J__ has been obtained from analysis of the PMR spectra of some 2โsubstituted azetidines and oxetanes. The absolute values of ^4^__J__~cis~ and ^4^__J__~__trans__~ were found to decrease with decreasing of th
