[U. of Ottawa NMR Facility Blog] Appropriate Choice of Presaturation Time
Appropriate Choice of Presaturation Time
Presaturation is one of the most common methods of solvent suppression. A long selective low power pulse is applied at the solvent frequency followed by a hard non-selective read pulse (or composite pulse). Aside from a well-shimmed homogeneous magnet, there are two important parameters required for effective presaturation: saturation power and saturation time. The selection of saturation power was addressed in a previous post. With a properly selected saturation power, the appropriate choice for the saturation time depends on the relaxation...

[Question from NMRWiki Q&A forum] Choice of relaxation delay time (d1) in 2D experiments.
Choice of relaxation delay time (d1) in 2D experiments.
Hi,
Most people tend to use a lower d1 for 2D than for 1D. Help me understand why.
Furthermore, supposing you know your T1 value, what do you think is the "best" (or most effective while having the shortest experiment time) value for d1 in a 2D experiment?
I'm not even sure my question makes any sense.

Computational approaches to the interpretation of NMR data for studying protein dynamics
Computational approaches to the interpretation of NMR data for studying protein dynamics
2 March 2012
Publication year: 2012
Source:Chemical Physics, Volume 396</br>
</br>
Experimental studies of protein structure and dynamics with NMR provide the classical example of the power of theoretical approaches for the interpretation of experimental results. In this paper we review recent developments in experimental techniques extending the applicability of NMR to the study of protein structure and motion, and advances in the theoretical description.

2H NMR Spin Relaxation for studying RNA dynamics
A Suite of 2H NMR Spin Relaxation Experiments for the Measurement of RNA Dynamics
Pramodh Vallurupalli and Lewis E. Kay, J. Am. Chem. Soc.; 2005; 127 (18) pp 6893 - 6901
ABSTRACT:
A suite of (2)H-based spin relaxation NMR experiments is presented for the measurement of molecular dynamics in a site-specific manner in uniformly (13)C, randomly fractionally deuterated ( approximately 50%) RNA molecules. The experiments quantify (2)H R(1) and R(2) relaxation rates that can subsequently be analyzed to obtain information about dynamics on a pico- to nanosecond time scale. Sensitivity...
