摘　　要：利用变温红外光谱中缔合羟基的非平面变角振动吸收谱带的变化 ,对 TAM- NPG二元体系在 37— 39℃的晶型转变机理进行了探讨。结合 DSC,证明组成随 TAM含量的增大 。Infrared spectroscopy at various temperatures for the binary systems of TAM NPG were determined and the mechanism of Solid Solid phase transition at 37-39℃ was discussed.Results of differential scanning analysis also proved that with the increase of TAM in binary systems the number of hydrogen bonds decrease.
