There are two classes of conformation in which the azacrown ethers exist in solution ac- cording to their molecular structure. Two kinds of intramolecular motion of the azacrown ethers were observed, one is the vibration of the macrocyclic ring and the other is its inversion. The ether rings which contain oxygens are more flexible than that constructed by nitrogens in the present case because of the tetrahedron structure of the nitrogen atoms and the hindrance of the groups Ts connected to the nitrogens. Some thermodynamical parameters of the ring inversion process were obtained.展开更多
