The use of appreciable H-D isotope effects in the infrared spectra of normal and deuterated salts of tri-n-octyl amine (TOAHX or TAODX, where X=Cl, Br, I, HSO4, NO3 and ClO4), the investigation of the chemical shift of the NH proton in NMR spectra, the results of chemical analysis (H2 O, D2 O acid) and the osmometrical data allow to explain some questions concerning the structure and to discuss the strength of the hydrogen bonds in associates TOAH+X and their hydration. From this comparison it follows that the strength of hydrogen bond in TOAH+X (TOAD+X) increases in the order of ClO 4 <HSO 4 <IBr<NO 3 <Cl. H-D isotope effects are discussed in the association of these salts.
