Abstract	2,2'-bipyridyl crown ether에 관한 allosteric 효과를 분자진동연구방법을 사용하여 연구하였는데, 방법으로는 mass-weighted-cartesian 좌표방법을 사용하였다. Crown ether의 pore opening 운동에 관여하는 모드로는 235, 234, 188 그리고 178cm-1에 해당되는 파수가 얻어졌고, biphenyl축을 통한 회전운동이 crown ether에 영향을 미치는 rotational vibration 운동은 168, 104 그리고 67cm-1에서 파수가 얻어졌다. 특히 178cm-1의 모드는 allosteric효과를 가장 많이 포함한 것으로 생각되어 진다. 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.
