multiplet

[′məl·tə·plət]
(quantum mechanics)
A collection of relatively closely spaced energy levels which result from the splitting of a single energy level by an interaction which is relatively weak; examples are spin-orbit multiplets and isospin multiplets.
(spectroscopy)
A collection of relatively closely spaced spectral lines resulting from transitions to or from the members of a multiplet (as in the quantum-mechanics definition).

Spontaneous motor-unit activity with bursts of doublet, triplet, or multiplet discharges is the main electrophysiological finding of IS (1,3,7).
If a multiplet is an off-shell representation of supersymmetry, as is generically the case for half-maximal or lower supersymmetry, there will consequently be no anti-fields in the cohomology.
Then pressing "M" did a multiplet fitting of overlapping peaks, "I" identified the nuclides and "Q" quantified the identified species.
Multidimensional NMR has allowed huge strides to be made in studies of the 3D structure and dynamics of complex molecules, but in each dimension the multiplet structure caused by homonuclear couplings sets the resolution limit.
Now there is no Bose-Fermi symmetry, since Bose and Fermi fields are not mixed in the same multiplet.
DVn now has patent priority for a wide range of applications that use monoscopic or multiplet source frames for combining images, when one uses blurring or defocusing for luminance modulation during image-stacking processing.
Previous measurements of an aerosol produced by a pneumatic nebulization of 25 nm spheres indicated a peak particle size corresponding to a multiplet of the primary spheres [31].
