Nuclear magnetic resonance spectroscopy (NMR)
Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique to observe local magnetic fields around atomic nuclei. The sample is placed in a magnetic field and the NMR signal is produced by excitation of the nuclei sample with radio waves into nuclear magnetic resonance, which is detected with sensitive radio receivers. The intramolecular magnetic field around an atom in a molecule changes the resonance frequency, thus giving access to details of the electronic structure of a molecule and its individual functional groups. As the fields are unique or highly characteristic to individual compounds, in modern organic chemistry practice, NMR spectroscopy is the definitive method to identify monomolecular organic compounds.
The Urban Dictionary Mug
Well madder nice print. 8 0z cup. I'd prefer a mug but will be ordering 3 more. Just my cuppa tea (or coffee). Americans always make fun of some of the things I say. Recently my brother and I were talking about the Trawna Maple Leafs. I decided to look it up and sure enough there is was Trawna the city I grew up in. Now who has the last laugh.
I ordered pink but got purple, and the text wasn't very clean, but overall, it is a mug.
It was a gift for my sister, who wrote it. She loved it and so did I!
