摘要
研究了液晶冠醚４＿（ω＿十一烯基氧）＿４′＿（４′＿羧基苯并＿１５＿冠＿５）联苯在升温时从晶态到液晶态再到液态的相转变过程中，其红外特征频率、相对强度及峰形所发生的变化。初步归属了该化合物的红外特征频率。
The changes of specific infrared frequencies, intensities and infrared spectra of liquid crystal crown ether 4_( ω _undecenyloxy)_4′_(4′_carboxybenzo_15_crown_5) biphenyl in heating process and in phase changing from crystalline to the liquid crystalline and then to the liquid phase have been studied. The specific infrared frequencies of the compound are summarized primarily and the relationship between spectroscopic characteristics and molecular structures are also discussed.
