| "Short relaxation times and small diffusion coefficients often impede reliable diffusion experiments due to insufficient signal to noise ratios, especially in low temperature studies, where in the case of small diffusion coefficients in combination with very short T(2) times and substantial convection, double-stimulated-echo experiments are required as last resort of convection-compensating DOSY pulse sequences." | ( Improved applicability of DOSY experiments by high resolution probes combined with gradient amplifiers of diffusion units.
