Abstract
Conventional dielectricε*(ω) data and solvation dynamic C(t) data are recorded simultaneously, assuring perfect coincidence of experimental conditions for the two relaxation phenomena in the glass-former 2-MTHF doped with quinoxaline. The dynamic MSA theory for dipolar solvation turns out to relate the observed Stokes-shift dynamics to the dielectric data in a quantitative fashion. The agreement between theory and experiment facilitates access to "microscopic" dielectric relaxation via spectroscopy of appropriate molecular probes in supercooled liquids.
