摘要: Vibrational lifetimes and absorption spectra of the asymmetric CO stretching mode (∼1990 cm−1) W(CO)6 in supercritical CO2 are reported as functions solvent density temperature. Close to critical temperature, observables independent over a twofold range density. Possible explanations discussed for this unique behavior.
