Graphical Abstract
Graphical abstract Research highlights
? We provide a complete and exact way of evolving the density matrix in NMR. ? This gives us a systematic way of calculating what goes on in any pulse NMR experiment. ? The method is based on a number of results from the quantum theory of angular momentum. ? Very little information on the wavefunctions, the operators that act on them, and their commutation properties is needed. ? Explicit formulae are presented for all the common NMR interactions: Zeeman, RF, scalar and dipolar coupling and quadrupolar interaction.

Speeding up direct 15N detection: hCaN 2D NMR experiment
Abstract Experiments detecting low gyromagnetic nuclei have recently been proposed to utilize the relatively slow relaxation properties of these nuclei in comparison to 1H. Here we present a new type of 15N direct-detection experiment. Like the previously proposed CaN experiment (Takeuchi et al. in J Biomol NMR 47:271â??282, 2010), the hCaN experiment described here sequentially connects amide 15N resonances, but utilizes the initial high polarization and the faster recovery of the 1H nucleus to shorten the recycling delay. This...

[Question from NMRWiki Q&A forum] How to set up 15N direct detection on UnityInova?
How to set up 15N direct detection on UnityInova?
Has anyone recorded directly detected 15N spectra on UnityInova? We have a triple resonance HCN probe. The sample I've used was natural abundance 1M NaNO3 - sodium nitrate.
I've tried to set up cable analogously to 13C detection - through the second preamp, but could not see any signal at all.

[Question from NMRWiki Q&A forum] What has been done with direct detection of Deuterium?
What has been done with direct detection of Deuterium?
Hello, I am trying to investigate what has been done in NMR using direct detection of deuterium in liquids. - Could you suggest any citations?
What kind of sensitivity gain there is in using broadband probe vs. lock channel?
Has anything been done/can be done to detect scalar couplings with protons like in COSY or TOCSY? Are HD couplings other than geminal detectable?
Thanks.
