Fermi symmetrization rules

Shriver and co-workers located the antisymmetric and symmetric stretching vibrations of the W-H-W bric%e at 1683 and 900cm , respectively. However, the latter splits into four bands at 960, 869, 832, and 702 cm . Although the origin of this splitting is not clear, the possibility of Fermi resonance with an overtone or a combination band involving the (WC) or 5(WCO) was ruled out based on CO-C 0 isotopic shifts. ...
