Crap. I nearly had a heart attack the other day. Absentmindedly, I burned an NMR in CDCl3 instead of C6D6. The shifts were all cattywompus. The atropisomerism I was expecting from the amide was nearly non-existent in deuterochloroform and my aromatic peaks were all flibbertygibbet. Cripes! This was no good at all!

So, I went to a nearby diner and thought about it over a plate of hashbrowns with onions, jalapenos, and cheese. While gnawing on the breath-busting composition, the problem of solvents dawned on me like an ice cream headache. Doh!!
