✦ Synopsis


Artifacts in the form of cross peaks have been observed along two-and three-quantum diagonals in single-quantum two-dimensional correlated (COW) spectra of several peptides and oligonucleotides. These have been identified as due to the presence of a non-equilibrium state of kind I (a state describable by populations which differ from equilibrium) of strongly coupled spins carried over from one experiment to the next in the COSY algorithm.

(1)H-detected two-dimensional double-/zero-quantum experiments are described for measurement of homonuclear (2)J(HH)-couplings of NH(2) or CH(2) groups in proteins. These experiments utilize multiple-quantum coherence for determination of the size and the absolute sign of the geminal scalar and dipo

The distributions of both the quadrupolar and the isotopic chemical shift interactions are shown to give multiple-quantum MAS spectra that remain tilted after shearing. For both types of distribution, the theoretical slopes, formed by the resulting distribution of the centers of gravity of the signa
