New NMR techniques are described for transferring transverse magnetization between scalar-coupled nuclei in the rotating frame. The methods involve simultaneous spin-locking of two selected spins A and X, using cosinusoidal modulation of the radio frequenc ...
An anal. was made of the effects of nonexponential transverse relaxation during the free precession periods of 2-dimensional NMR expts. The presence of cross-correlation between various interactions that cause relaxation, such as chem. shift anisotropy and ...
Cross-correlation between pairs of dipole-dipole interactions may lead to a partial conversion of longitudinal Zeeman magnetization into longitudinal three-spin order, which can be obsd. selectively by using a triple-quantum filter in conjunction with two- ...
Two-dimensional nuclear Overhauser enhancement (NOESY) spectra of labile protons were recorded in H2O solutions of a protein and of a DNA duplex, using a modification of the standard NOESY experiment with all three 90 degree pulses replaced by jump-and-ret ...
In applications to systems with resolved scalar couplings, the 2-dimensional exchange expt. (NOESY: nuclear Overhauser effect spectroscopy) can provide greatly increased information if the flip angles of the 2 pulses that precede and follow the mixing inte ...
The measurement of the migration of longitudinal 2-spin order by 2-dimensional (2D) exchange spectroscopy or by selective 1-dimensional (1D) methods (2D or 1D zz-exchange spectroscopy) allows unambiguous differentiation between chem. exchange and cross-rel ...
An improved procedure for pattern recognition in 2-dimensional NMR spectra is described. The algorithm uses only the signs of the signals, and begins by searching for responses that are characteristic of 3-spin subsystems, which are then identified as cons ...
Attention is drawn to a class of signals that appear if the rotation angles of the radio-frequency pulses in the 2-dimensional (2D) exchange expt. are inadvertently or deliberately set to b!=p/2. The signals (zz signals) arise from longitudinal 2-spin orde ...
The study of the diffusion of longitudinal scalar order in macromols. in isotropic soln. by 2-dimensional exchange spectroscopy provides addnl. insight into cross-relaxation pathways. [on SciFinder (R)] ...
