Popis:	The visible and infrared spectra of the 1 : 1 and 2 : 1 solid‐state complexes of hexamethylbenzene with tetracyanoethylene were investigated as a function of pressure up to 100 kbar. The degree of charge transfer is estimated as a function of pressure from the vibrational frequencies. A comparison with the visible spectra is used to check the internal consistency of the results. The observed pressure shift of the charge transfer peak is discussed in terms of the environmental and resonance contributions.
