Conclusions

  1. 1.

    The PMR spectra of solutions of hydrohalides of isomeric halobutylamines in trifluoroacetic acid and pyridine were studied.

     
  2. 2.

    The terminal methylene protons, found in theα- andΒ-positions to the ammonium groups, may possess magnetic nonequivalence, which increases from solutions in trifluoroacetic acid to solutions in pyridine.
