Default 31p-31p cosy

31P-31P COSY

I like to run a 31P-31P COSY experiment to determine whether there is coupling between 1R-31P-CH2-31P-X in my molecule. I already have 1H decoupled 31P-spectra, showing two very different chemical shifts for these two 31P. However, I never run 31P-31P COSY before, anyone have any advises. I have Bruker Avance II instrument. Thanks.

[Question from NMRWiki Q&A forum] 13c e.cosy
13C E.COSY Can somebody help me with the one query? How to record an E.COSY for solids proteins? Its possible to use available programme from bruker.but how to analyse the cross peak multiplets of 13C with mostly 1J 13C coupling? what is the best way to to obtain multiple bond J couplings in solids? Is quantitative J coupling methods suitable for solids? Is there a way of recording an CRINEPT without gradients in solids? Check if somebody has answered this question on NMRWiki QA forum

[Question from NMRWiki Q&A forum] CT COSY pulse sequence programming
CT COSY pulse sequence programming Hi, I want to make a CT-COSY pulse sequence. But I'm bother by incremented delay. When I type in the BaseLevelRelation.h this: IN=-INand add in the microprogram the delay before and after my pi pulse,it didn't work... It seems like it calculate the d28 delay from the IN28 increment, but doesn't want to apply this delay in the pulse sequence....Any idea ? Perhaps it's about some incrementation declaration or something like that ?

[Question from NMRWiki Q&A forum] COSY NMR limitations in the OsH-CH-CH chain
COSY NMR limitations in the OsH-CH-CH chain Is it correct that COSY (not long range COSY) in the OsH-CH-CH chain is demonstrating cross-peaks only for OsH-CH-CH and OsH-CH-CH fragments independently on J between protons in OsH-CH-CH? Check if somebody has answered this question on NMRWiki QA forum

[Question from NMRWiki Q&A forum] COSY problem
COSY problem Hi, I am running COSY on a DNA:RNA hybrifd. However, I have got no cross-peaks at all even for CYT H5-H6? what do you think the problem is? I am using cosydfesgpph as pulse programme. Thank you
