研究了两种对 -叔丁基杯 [6]芳烃的红外和拉曼光谱。对 -叔丁基杯 [6]芳烃 的环状的分子内缔合氢键和部分甲基化的 ( 1 ,3 ,5-三甲基 ) -对 -叔丁基杯 [6]芳烃 的三中心氢键在红外光谱中有明显反映 ,杯 [6]芳烃的 pinched cone(紧锥型 )构象也得到了证明。而两种杯 [6]芳烃氢键构象和强度的不同导致了二者的拉曼谱图也存在较大的差异
Infrared and Raman spectra of two p-tert-butyl calix [6] arene were studied. The cyclic intramolecularly associated hydrogen bonds of p-tert-butyl calix [6] arenes and the tris (3,5-trimethyl) The central hydrogen bond is clearly reflected in the infrared spectrum, and the pinched cone conformation of calix [6] arene has also been demonstrated. The difference of the hydrogen bond conformations and intensities between the two kinds of calix [6] arenes also lead to the large differences in the Raman spectra
