An NMR tube is a tube used in NMR Spectroscopy (used to detect molecule structures depending on peaks on a graph). Cleaning it usually uses acetone or dichloromethane and getting rid of it involves vacuum and maybe IR lamp. Organic chemists sometimes send samples to an NMR lab to get it back with the graph and detect if they got their product.

Steve: I cleaned the NMR tube with acetone.

NMR'd

Enamored (i.e., crushing on someone). Meaning derived from the sound made when pronouncing each letter: NMR'd = "En Em Ar'd" = Enamored.

Roommate #1: "Her Facebook status says, 'Janet is NMR'd.' What does that mean?"

Roommate #2: "That she wants it up the ass."

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.

Person 1: Do you think our laboratory needs an NMR-spectrometer?

Person 2: I've heard they're unbelievably expensive, but Nuclear magnetic resonance spectroscopy (NMR) is an essential analytical procedure for sure .
