Abstract

Piperidinium nitrate was studied by FTIR and FT Raman spectroscopy in the range 100-4000 cm-1 at 300 K. On the basis of DSC measurements which exhibit two effects indicating phase transition at 256 and 295 K, FTIR spectra were recorded down to a temperature of 90 K. Discussion of the phase transition mechanism is based on the observed changes in the FTIR spectra during cooling of the compound.
