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 .

Remnant King

remnant king
To master the are of leaving a piece of excrement in the toilet after you have flushed.

Picture rollin' in for your daily newpaper sitting. You have had your second cup of coffee & are growing a tail. Time to go relieve yourself. You open the door to your favorite stall & bam! A big old nugget sits there, with no toilet paper & no discolored water. All you can do is laugh, because the 'remnant king' has struck again.

Resonance

The song that makes you forget that the world is shitty for three minutes.

Sam: I hate my life. I'm gonna listen to Resonance.
John: Don't leave me out! I want to forget that life sucks too!

remoralise

To raise a person's morale after it has been previously lowered, generally with the intent of lowering it again immediately after. To lift someone up so they have farther to fall back down. The opposite of demoralise.

henry: Why are you losing on purpose?
tom: I am going to remoralise him so when I win he will be more demoralised.

remoras

A person's remoras are a personal retinue of sycophants that maintain the fragile esteem of an important person and bask in that person's reflected glory. They do not serve some instrumental purpose. such as bodyguards or assistants, but are merely a mobile personal cheering squad.

You can always expect that stars and media celebrities with have their remoras in tow.

A name giving to the nicest person you could ever hope to meet. Welcoming and thoughtful Ramona is the girl everyone one wants to meet, but few really know. Why? That can’t be answered because she is sincerely one of the most kindhearted people they could possibly find in the world today.

A sweet smile, lovely voice, and pure heart make her a must in everyone’s life. Amazing taste in music, clever, and driven, she will be someone of great acknowledgment, she’s going to make a difference and change the world. Uninfluenced from others and always thinking with a clear mind she is the best at giving advice. She is there to stand up for herself and others. Her kind ways are sometimes taken advantage of but she learns from her past and is heading to a bright tomorrow. If you meet her, you remember her, and think of her often. She is the pretty girl with the best personality. She is the girl that you stared at in class. The girl that once you met her you can’t help but liked her. The best secret keeper. She is the definition of a good person. Also answers to Mona.
