Title: 1H NMR spectrum interpretation
Post by: knur997 on October 15, 2018, 03:43:20 PM

Hello! I have synthesised paracetamol and now I want to check its quality, I did NMR spectroscopy but I can't really see more than methyl group and aromatic ring. And I believe that integration values are far from right. Could you show me how to identify the compound? (https://iv.pl/images/12142947614265337815.png)

Welcome to the forum.  You must show your attempt before we can help you (see red link above).  I will give you a small hint.  Integral values are relative and generally have to be calibrated.

I would start with figuring out, which is the solvent peak (in your case acetone-D6) and "remove it" from the spectra (ie. cross it over or something so you know it doesnt belong to your compound)
