What are these things?! All the lines! Splitting? Integration? This is the most confusing thing I've ever seen! OK, take it easy chief. Let Professor Dave take you through the very basics of interpreting NMR spectra.

That's because these folks are always like "Now, lets explain this with quantum mechaincs" and start shooting some formulas and differentials around the subject and you're losing half of the point because you don't remember them xD It's like they're guiding you through some forrest, talking about the great view and flowers and trees around, meanwhile you're standing there, watching all this stuff and wondering, if you're standing on a path

I learned now first time to understand why different hydrogens in certain functional groups have such peaks they have. God bless you and many thanks.

In the horse-and-buggy days of NMR, I was the NMR operator/maitainer (because of my electronics training. I had a very poor understanding of biochem). We had a Jeol C-60 unit, a Japanese import having hybrid vacuum-tube and solid-state electronics. It used an electric field magnet with a "superstabilizer" to minimize fluctuations in the field strength. The magnet was cooled with refrigerated deionized QDW. It could perform both frequency and field-sweep spectra. The purpose was to aid our biochem department in analyzing the structure of DNA with an eye toward cancer research. Lyons-Kettering Research Center at the University of Alabama at Birmingham in the late 60's/early 70s. I left because I was a "fish out of water": The only employee there without at least a Master's.
