Nonrigid Group Theory of Water Clusters ( Cyclic Forms): (H2O)i for 2 < i < 6

The character table of the fully nonrigid water cluster (cyclic forms), (H2O)i, with Cih symmetry derived for the first time, for 2 < i < 6. The group of all feasible permutations is the wreath product of groups Si[S2] which consists of i!2i operations for i = 2, ..., 6 divided into ( w.r.t) 5, 10, 20, 36, 65 conjugacy classes and 5, 10, 20, 36, 65 irreducible representations respectively. We compute the full character table of (H2O)2, (H2O)3, (H2O)4, (H2O)5 and (H2O)6.
