In the synthesis experiment, the product shows 3 carbonyl stretching frequencies in the infrared spectrum, at 2021, 1898 and 1840 cm-1. Determine the irreducible representations of the stretches expected for each of the two species in their respective point group. Can you confirm what isomer was isolated?

Question
Tungsten hexacarbonyl (W(CO)6) is reacted with (EtC≡N) and the product is W(CO)3(N≡CEt)3.
However, the product can be a mixture of fac and mer isomers. But a Chemist can determine from
analysis of the infrared spectrum if the product is indeed a mixture of isomers or not. In the
synthesis experiment, the product shows 3 carbonyl stretching frequencies in the infrared
spectrum, at 2021, 1898 and 1840 cm-1.
Determine the irreducible representations of the stretches
expected for each of the two species in their respective point group. Can you confirm what isomer
was isolated?
