| Abstract: | Phase transition in L-alaninium oxalate is studied by using TG, DTA and photoacoustic spectroscopy. A sharp transition at
378 K by photoacoustics is observed whereas at the same temperature the endothermic energy change observed by TG and DTA is
not very sharp. This is discussed in detail with reference to the other known data for the organic crystals. |
