[Question from NMRWiki Q&A forum] why is the number of scans in watergate a multiple of 8?
why is the number of scans in watergate a multiple of 8?
Hi,
In the p3919gp the number of scans is a multiple of 8 which makes optimizing this experiment a bit of a pain. can anyone explain why ns needs to be a multiple of 8
thx

Abstract
The heme in cytochromes c undergoes a conserved out-of-plane distortion known as ruffling. For cytochromes c from the bacteria Hydrogenobacter thermophilus and Pseudomonas aeruginosa , NMR and EPR spectra have been shown to be sensitive to the...

Authors: Grishaev A, Llinas M
The NMR-generated foc proton density affords a template to which the molecule has to be fitted to derive the structure. Here we present a computational protocol that achieves this goal. H(N) atoms are readily recognizable from (1)H/(2)H exchange or (1)H/(15)N heteronuclear single quantum correlation (HSQC) experiments. The primary...

[Louic Vermeer blog] Using procheck_nmr on a large number of structures
Using procheck_nmr on a large number of structures
After a structure calculation with the aria 2.2 software I used aqua and procheck_nmr to assess the result. Although procheck_nmr worked fine on my 20 refined structures (in aria’s refine directory), it ran into trouble with the 100 structures after iteration 8 (directory it8): * Restraints read in from file: * allpdb.nrv

peak intensity vs number of scans
Hi,
I have a question regarding how the peak intensities change when with increase in number of scans when the data is collected on a Varian NMR spectrometer. Suppose I collect a 15N-1H HSQC spectra with 8 scans and then collect the same spectra with 16 scans, would the peak intensities be double in the 16 scan spectra as compared to the 8 scan spectra? Does anyone know how the varian spectrometer scales the intensities according to the number of scans? Any suggestion or reply to my query will be extremely useful and greatly appreciated.
Thanks.
