摘要
采用变温红外光红外技术在303-393K范围内,分别测定二苯甲酮羰基伸缩振动(νC=O)的一维红外光谱、二阶导数红外光谱及去卷积红外光谱。实验发现:二苯甲酮相变的临界温度为325-326 K,并进一步研究了其相变机理。
The temperature effect of benzophenone is studied by one-dimensional infrared spectroscopy,second derivative infrared spectroscopy,and deconvolution infrared spectroscopy in the temperature range from 303 K to393 K. The critical temperature of phase transition is 325-326 K,and the phase transformation mechanism is further discussed.
