Abstract
Two-dimensional Fourier-transform ESR spectra from a complex fluid cha racterized by very short free induction decay times are reported. They provide enhanced resolution to dynamic molecular structure compared t o conventional cw-ESR spectra which are inhomogeneously broadened by t he macroscopic disorder. A general theoretical analysis based on the s tochastic Liouville equation permits us to accurately determine the mi croscopic ordering and motional dynamic rates by non-linear least-squa res fitting to experiment.
