They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Applications in Protein NMR As previously mentioned, the major advantage of 2D NMR over 1D NMR is the ability to distinguish between the overlapping signals that exist in larger molecules. Much emphasis is placed on the discrimination of different distributions. and physical changes caused by coalification making this parameter a good indicator of coal. Relations between specific iso-paraffinic structures responsible for very high viscosity index and low pour point are discussed in terms of mobility behaviour and spin-lattice relaxation time measurements. Complex pulse sequences are constructed with control pulses sent from module to module down a sequential hierarchy: the ability of each channel to loop a predetermined number of repetitions at a set rate, while producing resetting and initiating pulses to the next channel allows the production of repetitive sequences, such as the Carr–Purcell and the saturation burst.
