The following table lists infrared (IR) carbonyl stretching frequencies for three organometallic complexes. Explain why the infrared frequencies increase as one proceeds down the series.
[V(CO)6] - 1860 cm-1
[Cr(CO)6] 2000 cm-1
[Mn(CO)6]+ 2090 cm-1
As you go down the series, the positive charge of the nucleus of the ...
