โฆ Synopsis
Intramolecular exciplex formation of p(N,N-dimethylaminophenyl) (CH,),( 9-anthryl) in supercritical fluids of ethylene and trifluoromethane at 30ยฐC has been investigated. The wavelength of the exciplex fluorescence band maximum in trifluoromethane is not affected by the density of the fluid, on which the dielectric constant as well as refractive index of the medium may depend.
