Abstract : Several aromatic hydrocarbons are complexed with trinitrobenzene (TNB) and trinitrofluorenone (TNF) in the crystalline state and subjected to increasing pressures (0-30 kbar). The charge transfer absorption shows a approx. 1200/cm red shift, while the fluorescence red shift may vary between 200-1700/cm at 25 kbar. In the same complexes the Stokes shift decreases at higher pressures. This decrease can be understood in terms of charge transfer forces and potential energy curves appropriate for weak EDA-complexes. (Author)
