[Question from NMRWiki Q&A forum] Methanol-d in chloroform-d
Methanol-d in chloroform-d
Hi,
This is a question related to the question I posted earlier titled "H NMR integration". I tried adding one drop of methanol-d (99.0% atom %D) using a regular pipet to the chloroform-d solution of polymer, hoping that the proton in water can exchange with methanol-d so that the water peak can vanish. Although only a very small amount of methanol-d was added, the NMR spectrum is dominated by the proton signal from CH3 group of undeuterated methanol at ~3.5 ppm. I'm wondering how to reduce the signal of this peak? Just reduce the amount of methanol-d?Thank...
