Absorption spectra of the CT band of I<SUB>2</SUB> complexes were observed in several nonpolar solvents at 1 bar, and in heptane up to 4400 bar. All solvent shifts were red with an increase in (<I>n</I><SUP>2</SUP>−1)/(2<I>n</I><SUP>2</SUP>+1), the refractive index (<I>n</I>) function of solvents, consistent with the solvent shift theory. On the other hand pressure caused a variety of shifts, that is, red shifts in benzene–, toluene–, and mesitylene–I<SUB>2</SUB> complexes, an inversion shift from red to blue in HMB–I<SUB>2</SUB> complex, and blue shifts in Et<SUB>3</SUB>N–, <I>n</I>-Pr<SUB>3</SUB>N–, and <I>n</I>-Bu<SUB>3</SUB>N-I<SUB>2</SUB> complexes, though increase in pressure invariably raises the (<I>n</I><SUP>2</SUP>−1)(2<I>n</I><SUP>2</SUP>+1) value of solvent. The pressure shifts of I<SUB>2</SUB> complexes seem to be interpreted by a sum of two effects. One is the increased polarity of the solvent, which causes a red shift. The other is the decrease in the bond distance between a donor and an acceptor, which contributes to a blue shift in a strong CT complex and to a red shift in a week one. The pressure and solvent shifts of I<SUB>2</SUB> complexes were compared with those of π-donor–TCNE complexes.
