Method and apparatus for treating a sample to acquire multidimensional
spectra within a single scan that partitions a sample into a set of
independent subensembles endowed with different resonance frequencies. A
polychromatic irradiation of the sample is implemented whereby the
various subensembles are selectively manipulated by a time-incremented
series of excitation or refocusing sequences. Thereafter, a homogeneous
sequence capable of generating an observable spectral signal from each of
the subensembles is applied with simultaneous monitoring of the
observable signals arising from the various subensembles in a resolved
fashion. the observable signals acquired in this manner are processed
into a complete multidimensional spectral data set.
