结论温度、状态和稀释度的变化对二氯丙酮红外光谱和拉曼光谱的影响可以通过两种旋转异构体来合理解释。极性较强的同分异构体在固态中存在，在液态中能量也较低。液体的能差下限为1500卡/摩尔。在气相中，极性较低的种类比其他异构体丰富得多，这表明从液体到气体的相对稳定性发生了逆转。由于各种可能的同分异构体的选择规则相似，这两种同分异构体的分子对称性尚未确定。华盛顿特区25号
Conclusions The effects of changes in temperature, state and dilution on the infrared and Raman spectra of dichloroacetone can be reasonably explained on the basis of two rotational isomers. The more polar isomer persists in the solidstate and is also of lower energy in the liquid. The lower limit for the en-ergy difference in the liquid was found to be 1500 cal./mole. In the gas phase, the less polar species is much more abundant than the other isomer, indi-cating a reversal in relative stability in going from liquid to gas. The molecular symmetries of the two isomers have not been determined due to the similarity of the selection rules for the various conceivable iso-mers. Washington 25, D. C.
