Abstract
Time resolved phosphorescence spectrocopy of molecular probes in organic supercooled liquids indicates solvation dynamics active on the ms-s time scale. A detailed analysis of the positive solvatochromism of quinoxaline allows for experimentally quantifying the change in dipole moment upon T 1 <-S 0 excitation and the polarity of supercooled liquids. Solvation in marcroscopically unpolar solvents indicates the important role of microscopic polarity for rationalizing the local dielectric responses governing the solvation dynamics
