Abstract
|
|
|
|
By using the Mass-Weighted-Cartesian coordinate method, the allosteric effect of 2,2'-bipyridyl crown(4) ether is studied. The vibrational modes of 235, 234, 188, and 178cm-1 belong to the pore opening motion of crown ether and those of 168, 104, and 67cm-1 belong to the rotational vibration motion of bipyridyl. Especially the mode appearing at 178cm-1 shows a large allosteric effect by activation of the allosteric site.
