The symmetry group of nonrigid tetramethylsilane

摘要

Using nonrigid group theory, it is shown that the full nonrigid (f-NRG) group of tetramethylsilane is isomorphic to the group C-4 similar to S-4 of order 1944, where "similar to" denotes the wreath product of groups, and C, and S-4 are the cyclic group of order three and the symmetric group of order four, respectively. This group has 51 conjugacy classes and irreducible representations. Then the character table of tetramethylsilane is derived for the first time. (C) 2007 Wiley Periodicals, Inc.
