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 .

NUCLEAR CARL

Microwaving a piece of dog shit on high for 5 minutes at a party where you don't know anyone. This REALLY stinks, especially if the dog is old or sick!

"That party was wack, So I set off a Nuclear Carl"

Nutella ponchik

A deep fried dough with nutella filling inside, kuklas usually buy a box and put it on the hood of their BMW or Mercedes and upload a picture and post on ig.

Axchi let's go buy some Nutella ponchiks and take pictures of it and upload it. Make sure our car is in it so all the guys will add us after papillon bakery posts us on their page.

Nuclear fusion explosion

Nuclear reaction which happens when Kim Kardashian farts. It is caused by extreme pressure between the cheeks of her butt, which forces hydrogen atoms to fuse with one another, creating a chain reaction which annihilates all forms of life from the surface of Earth, except her followers.

- Daaamn have you seen that nuclear fusion explosion?

- Eh, probably Kim Kardashian ate some lime beans again.
