It’s not that difficult to run once you understand the quirks of the user interface. It’s not perfect but it’s a heck of a lot better than not
having any NMR

If you integrate one of the 1 proton peaks of the ibuprofen instead of the acetone as your “1.00”, assigning the ibuprofen peaks will be much
easier, and you could roughly quantify the amount of the residual solvents in your sample. Looks great though!
Also I’m going to go ahead and merge this with your other thread. I don’t see why two are needed.

Thanks! It has been a good 10 years since I last worked up NMR data myself so I’m very rusty.

I went back and did the integration like you suggested and it worked like a charm. Molar ratio calculation is as follows:
Ibuprofen: 1
DCM: 0.1678
Acetone: 0.4572
If I back calculate from the molar mass then the Ibuprofen should make up 83.49%, the DCM is 5.77%, and the acetone is 10.75% by weight.

Cool, could you post an image of the updated spectrum?
