Effects of various solvents on the infrared spectra of propanoic acid   were studied. Fundamental vibrations  v(0-H), &(0-H)   and   v  (C-O)    were  investigated  with  respect  to solvent change.    The  v  (C=O)   vibration  was  also  studied   in  a binary   mixture  of  carbon tetrachloride and acetonitrile. Results were interpreted in terms of solute-solvent interactions.
