Abstract in another language

The method of hole burning spectroscopy is an excellent means to investigate small shifts and broadenings of quasi-homogeneous optical lines of dye molecules embedded in an amorphous matrix, caused by slight changes in the microscopic matrix environment after applying hydrostatic pressure. We have investigated the pressure-induced line shifts of free-base phthalocyanine in the polymer matrices polyethylene and polystyrene. The experimental data confirm the theoretical prediction of Laird and Skinner pertaining to the frequency dependence of the pressure-induced shifts and the corresponding broadening effects of spectral holes.
