[Question from NMRWiki Q&A forum] Topspin 3.2.1 - 1D TOCSY in with differing mixing times
Topspin 3.2.1 - 1D TOCSY in with differing mixing times
Hello,
I work a lot with compounds containing numerous carbohydrate groups. Therefore I use frequently 1D-TOCSY experiment with varying mixing times (parameter d9 = 30, 60 and 120 ms for selmlgp pulse program). It would be very useful to have a pseudo-2D experiment with these 3 1D-TOCSY spectra saved as one ser file (I remember that it was possible on Varian instruments).We've got a Bruker 500 MHz apparatus with Avance III HD console. Topspin version 3.2 pl1.Can you help me with creating such experiment? Is it even...
