The spectroscopic study of intramolecular hydrogen bonds of a large nu!nber of compounds was developed by Wulf et al (1). They showed that the change in frequency of vibration occurs at about 7000 cm-l (in wave-number units) corresponding essentially to th? stretching of O-H and N-H bonds in molecul

## Abstract Chemical shifts of Hβbonded protons in tetrabutylammonium hydrogen maleate and 14βsubstituted picolinic acid __N__βoxides have been measured in a number of dry solvents, of different activity, in order to distinguish between symmetrical single minimum and asymmetrical hydrogen bonds. In
