Abstract

The magnitude of the shift in the v(CO) IR spectrum of the MLCT excited state of [Re(CO)₃Cl(bipy)] (bipy = 2,2′-bipyridyl) in PrCN-EtCN solution, compared with the ground-state spectrum, decreases on cooling from fluid to glass; this 'infrared rigidochromic' effect is explained by the change in character of the MLCT state on glass formation.
