Electric-field-induced spectral matrix-shift variations of perylene in non-polar matrices

We determined the electronic level shifts and the effective electric dipole moment differences of perylene in non-polar and polar matrices from the changes of spectral holes in an external electric field.

Description
Summary:We determined the electronic level shifts and the effective electric dipole moment differences of perylene in non-polar and polar matrices from the changes of spectral holes in an external electric field. The effective dipole moment differences of perylene in the non-polar matrices polyethylene, solid paraffin oil and n-octodecane are about one order of magnitude smaller than in the polar matrices polyvinylbutyral and butanol. The observed frequency shifts in the non-polar matrices, which depend linearly on the electric field strength, are attributed to electric-field-induced variations of the gas-to-matrix shift of the electronic levels of perylene.
