🧲💦 Multiple solvent suppression using the WET sequence. The experiment was run in fully automatic mode. This is a very useful sequence that can be used as a building block for any further 2D experiments (COSY, HSQC, NOESY, HMBC etc.)

💧🧲 Part III of our water suppression series. Excitation Sculpting. Standard water_ES parameter set was used (OpenVNMRJ software). There are a lot of variants of ES e.g. in Bruker TopSpin pulse sequences library.

Can you assign the couplings?

🧲❗️The answer to the previous challenge. The key factor is the coupling constant of the proton bonded to the anomeric carbon to the neighbouring ¹H. This proton is readily identifiable at higher frequencies in the ¹H NMR spectrum.
