## Abstract The change in ^1^H NMR chemical shifts upon hydrogen bonding was investigated using both experimental and theoretical methods. The ^1^H NMR spectra of a number of phenols were recorded in CDCl~3~ and DMSO solvents. For phenol, 2β and 4βcyanophenol and 2βnitrophenol the OH chemical shift
## Abstract The chemical shifts of hydrogen bonded protons in complexes of 11 substituted pyridines with trifluoroacetic acid were examined, in five dry solvents of different activity, with respect to proton transfer and aggregation effects. The results were correlated with Ξp__K__~__a__~, the Kirk
