Abstract
A new type of two-dimensional electron-spin-echo (2D-ESE) spectroscopy was recently shown to be useful for studying slow molecular motions in liquids. A recently developed method of spectral enhancement based upon linear prediction with singular value decomposition (LPSVD) is applied in the present work to dramatically improve the signal-to-noise ratio and to correct for finite dead time in the data from this 2D-ESE experiment. This permitted a more accurate comparison between theory and experiment. Good agreement is now obtained with a model of nearly isotropic Brownian motion for tempone in glycerol/water solvent.Keywords
