## [**THE ONE TABLE TO RULE THEM ALL**](http://ccc.chem.pitt.edu/wipf/Web/NMR%5FImpurities.pdf?ref=chemissst.com)

I don't REALLY think I need to post about this, but in the interest of sharing cool stuff, the NMR impurities paper is the end-all be-all of all desk flotsam. My first time using this was definitely in undergrad, but the first time I had this hanging up at my desk I was a little baby B.Sc. analytical chemist working in QC. We supported some R&D activities so we had to actually integrate spectra without knowing what the structures were...  
  
Anyway, I have had the same one of these hanging up since grad school. It's got coffee stains on it.
