Introduction,rs, and data storage devices, enable the user to perform routinely many multipulse experiments with a time expenditure no longer significantly exceeding that of most traditional techniques, as for instance, multiple selective decoupling. On the other hand, much more information can be extracted from multipulse than from conventional measurements.

Exercises,is closely follows actual practice, since prior to taking an NMR measurement it is normal laboratory procedure to have on hand the chemical history of the compound and information derived from other spectroscopic methods.

Exercises, high-resolution mass spectra, and so forth. Often the constitution formula is given, and sometimes statements about the configuration are offered. This closely follows actual practice, since prior to taking an NMR measurement it is normal laboratory procedure to have on hand the chemical history of

Strategies,elative value of each single piece of information. There are “soft” clues or hints that can only be evaluated through experience and a knowledge of analogous findings, that is, on the basis of empirical evidence. A typical example is the evaluation of the chemical shift . of an atom by taking into a
