HOOCl-H₂O Cluster의 구조와 결합에너지에 대한 ab initio 연구 = Ab Initio Study of the Structure and Binding Energy of HOOCl-H₂O Cluster

국문 초록 (Abstract)

HOOCl-H2O cluster에 대하여 안정한 구조와 결합에너지를 MP2/6-311G(d,p), MP2/6-311G(2d,2p)의 방법으로 계산하였고 vibrational frequency계산을 하여 HOOCl의 vibrational frequency와 비교하였다. Skew HOOCl-H2O cluster가 가장 안정한 cluster로 나타났고 결합에너지는 46~48 kJ/mol 정도이며 trans HOOCl-H2O cluster의 경우도 이보다 불안정하나 비교적 큰 결합에너지를 갖는 것으로 나타났다.

The geometrical structure, binding energy and vibrational frequencies of HOOCl-H2O cluster were investigated with MP2/6-311G(d,p) and MP2/6-311G(2d,2p) methods. The most stable conformer is skew HOOCl-H2O cluster and the binding energy was 46~48kJ/mol. The trans HOOCl-H2O cluster is less stable than skew form, but the binding energy is big enough to stablize the complex. The vibrational frequencies of skew and trans HOOCl-H2O cluster were calculated and compared with the spectrum of HOOCl.
