✦ Synopsis

A procedure is described for obtaining NMR correlation information by simultaneous excitation of several chemical sites with selective radiofrequency pulses that are phase alternated according to a Hadamard matrix. Individual correlation spectra are separated by recombining these scans with the corresponding permutation of signs. This scheme enjoys high sensitivity while performing much faster than the analogous two-dimensional methods.

## Abstract A gradient technique to measure electron paramagnetic resonance spectra simultaneously at several different locations is described. The technique is based on the use of point probes containing paramagnetic centers. The value of the magnetic field gradient is chosen to be sufficient to s
