Abstract
A method to obtain dipolar information for nuclei exhibiting ultra wideline NMR spectra in disordered solids is presented. This is achieved via a constant time version of SEDOR (spin echo double resonance) employing WURST (wideband uniform rate smooth truncation) pulses and CPMG (Carr Purcell Meiboom Gill) detection. The method – coined constant time WUDOR (WURST SEDOR) NMR spectroscopy – is tested on two crystalline model compounds (31P{19F}-CT-WUDOR NMR and 31P{19F}-CT-WUDOR CPMG NMR on Na2PO3F, 125Te{31P}-CT-WUDOR CPMG NMR on Ba2(PO4)2TeO) and applied to obtain structural information on TeO2 – NaPO3 – NaF glasses.
