E-mail address: [email protected] (L Few analytical techniques rival the capabilities of two-dimensional nuclear magnetic resonance. A scheme enabling 2D NMR acquisitions within a single-scan has been recently demonstrated, based on combined field gradient and radiofrequency manipulations. Distortions were observed upon implementing such ‘ultrafast’ experiments on solids undergoing magic-angle-spinning, presumably due to interferences arising between the periodic time-dependencies involved in the mechanical and in the spin manipulations. Experimental and numerical setups were designed to investigate these effects, and to find conditions that minimize them. When devoid of these non-idealities, quality 2D NMR spectra could be retrieved from spinning polymers within a single-scan. 2008 Elsevier B.V. All rights reserved.
