Abstract
Four phases in the temperature interval 312 and 77 K are observed in the infrared and Raman spectra of the title compound. The phase changes concern the proton potential function of the short hydrogen bond connecting both carboxylate moieties. The optical spectroscopic observations are correlated with literature NQR and our own DSC data.Keywords
