A technique is dcrcribcd for the selective detection of multiple quantum transitions by means of two-dimensional spcctroscopy. The separation of various orders of transitions is based on characteristic transformation properties of multiple quantum transitions permitting an orthogonal expansion of t

## Abstract ^1^H multiple quantum (MQ) NMR spectra of toluene and __p__‐bromotoluene, partially aligned in a liquid crystalline solvent, were acquired using gradient‐assisted methods. The MQ spectra were analysed to give the dipolar couplings (__D__~__ij__~) and these were used to determine the mol
A new strategy is described for analyzing the NMR spectra of spectra, depend on the same Hamiltonian, and so contain molecules dissolved in liquid-crystalline phases. The multiplethe same information. The computation of the frequencies quantum spectra which involve a change in the magnetic quanof th
Homonuclear N S ؍ 0 and heteronuclear N S 0 multiple quantum spectra, involving changes in the magnetic number m I by (N I ؊1), (N I ؊ 2), and (N I ؊3), with N I and N S the number of interacting nuclei of magnetogyric ratio ␥ I and ␥ S , are used for the automatic analysis of 1 H NMR spectra of f
