Default Anti-diagonal artefact in DQF COSY (Varian dqcosy.c)

Anti-diagonal artefact in DQF COSY (Varian dqcosy.c)

Hi I have the following problem in dqfcosy - have pretty strong antidiagonal.

I've run the same experiment before on other samples and did not have this problem, could you suggest anything? Is there any other pulse sequence in the Varian toolchest superior to this one?

... but probably something is just wrong with my setup, it is a really simple sequence though and I thought it would be hard to screw up :). Or is it normal and I just have low S/N?

edit: I've figured out that in this case I had receiver overflow. To test that go to the .fid directory of the experiment and inspect file called log.

[Question from NMRWiki Q&A forum] 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. Check if somebody has answered this question on NMRWiki QA forum

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
