We propose a robust band-selective heteronuclear 15N-13C recoupling method using dual back-to-back (BABA) pulses (DBP). It contains four 90° pulses in each rotor period and corresponding phase cycling on each channel (13C and 15N). DBP aims at rapid band-selective heteronuclear magnetization transfer between 15N and...

[Question from NMRWiki Q&A forum] Translating Varian to Bruker, "phase=1,2"
Translating Varian to Bruker, "phase=1,2"
I'm trying to translate a Varian pulse sequence into a Bruker pulse program. For the Varian Inova sequence with the parameter setting "phase=1,2" (hypercomplex, States-Haberkorn), several of the pulses in the pulse cycle appear to have two phases (see below). First question: does this mean that the cycle on each transient is executed twice, and that the phases are changed for only certain pulses within that transient? Second question: does anyone know how to implement this on a Bruker Avance?

Abstract
The backbone assignment of medium-sized proteins is rarely as straightforward as that of small proteins, and thus often requires creative solutions. Here, we describe the application of a combination of...

[Question from NMRWiki Q&A forum] Translating 31P NMR references
Translating 31P NMR references
Hello,
I am trying to compare different 31P chemical shift data from a variety of literature sources. However, each of these sources references their data in a different way.
Is there a table somewhere that I could translate 31P shifts taken with DSS to TMP or TSP or phosphoric acid or water?
I've been asking around in the real world and many people are telling me that this data should exist somewhere but neither I nor any of them are able to find out how to convert this data.
