Hydrogen bond patterns in solid state carboxylic acids. Vibrational behaviour of the catamer pattern as exhibited by the N-alkyloxamic acids

Article abstract of DOI:10.1016/0584-8539(96)01689-3

The vibrational study presented in this publication shows that the N-alkyloxamic acids are hydrogen bonded through a catamer hydrogen bond pattern in the solid state. Two different hydrogen bond patterns are possible for these products, and these patterns can be very clearly distinguished by their vibrational behaviour. Deuteration and low temperature spectra make the assignment and characterisation more obvious.
