Douglas H. Moraisrs. Understanding them doesn‘t really mean only being able to use them. A lot of people can use them without understanding them." Christopher Strachey The development of programming languages is one of the finest intellectual achievements of the new discipline called Computer Science. And yet, there

Douglas H. Moraisnalysis is quite satisfactory for determining the appearance of the one-dimensional NMR spectrum of the coupled spins. However, this approach is completely impractical for calculations on an ensemble of spins that are subject to multiple excitation pulses in typical NMR experiments. Consequently, we

Douglas H. Moraisatoms. Therefore, these couplings can be utilized to correlate NMR signals of atoms that are chemically bonded to one another, providing chemical shift assignments if the molecular structure is known. In particular, the scalar coupling across the peptide bond permits the linkage of spins within one

Douglas H. Moraisistence of such a peak indicates that the participating spins are coupled to one other by scalar (J) coupling through chemical bonds or via dipolar coupling through space. The position of the peak is defined by the chemical shifts, or resonance frequencies, of the coupled spins..In this chapter we w
