报道了大环化合物1，10-二氮-18-冠-6-(氪22)、单氮杂-18-冠-6和18-冠-6(18C6)及其与Na+和Ag+的络合物在25℃下的超声弛豫谱和红外光谱(N-H拉伸)。弛豫谱归因于大环配体不同构象之间在微秒到纳秒时间尺度上的分子内转换
Ultrasonic relaxation spectra and infrared spectra (N-H stretch) are reported for the macrocycles 1,10-diaza-18-crown-6-(Kryptofix 22), monoaza-18-crown-6, and 18-crown-6 (18C6) and their complexes with Na + and Ag + in the solvent propylene carbonate (PC) at 25 o C. The relaxation spectra are attributed to intramolecular conversions on the microsecond to nanosecond time scale between various conformers of the macrocyclic ligands
