Using nonrigid group theory, it is shown that the full nonrigid (f‐NRG) group of tetramethylsilane is isomorphic to the group C 3 S 4 of order 1944, where “” denotes the wreath product of groups, and C 3 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. © 2007 Wiley Periodicals, Inc.
