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 .

spectrophilia

1. Sexual attraction to ghosts.

2. Engaging in sexual activity with a ghost.
Tom is known to have had some spectrophilia in the past.

Gay Spectrum

Just like the Electromagnetic Spectrum (go to Wikipedia you mediocre dunces), the Gay Spectrum lists various wavelengths of Gayness - according to the longest-lasting wavelength of Gayness and the highest frequency of Gayness i.e. strongest.
Randomer 1: Where would you place him on the Gay Spectrum?
Randomer 2: Oh no! The Gay-mma rays burn!!!

Spectro-Pedophilia

Getting your sex on with a little ghost.
Wanting to bone Casper the ghost, would be the perfect example of Spectro-Pedophilia..

Spectrum Boy

Somebody who isn't obviously stricken with autism or Aspergers, but falls somewhere on a spectrum of special-ness.
Person A: "Why is that kid part of the special-ed class? He looks perfectly fine."
Person B: "He doesn't have severe autism or anything, but he's a bit of a Spectrum Boy."

autism spectrum disorder

A neurodevelopmental condition characterized by impaired social skills and restricted interests or repetitive behavior. Symptoms usually begin in early childhood.

Although most people with autism spectrum disorder (people "on the spectrum") are functionally impaired, some thrive occupationally or academically, especially people with Asperger's syndrome, who have no delays in language development and/or IQ.

A common misconception is that people on the spectrum lack empathy, the affective part of empathy seems to be unimpaired compared to people without the condition. This means that people on the spectrum often have the capacity for compassion and morality.

Complications include bullying, unemployment (prevalence of about 90%), suicide and self-harm.

Treatment is limited and the efficacy of specific interventions has been disputed.

The heritability of the condition is about 90%. Specific environmental risk factors known to contribute to the condition include autoimmunity. Disproven environmental factors include vaccines.

Although the condition causes significant suffering for many, some have disputed the characterization as a disorder altogether, especially because the restricted interests commonly seen in the condition can include occupationally or socially useful subjects like math or physics. People on the spectrum often hyperfocus on their area of interest.

Several historical figures like Einstein are claimed to have been on the spectrum, these claims are unproven.
Autism spectrum disorder has a prevalence of about 1%.

Spectrum

A cashgrabbing, penny-whoring, satanic reincarnation of Time Warner Cable that gives retarded prices for retarded products for the purpose of trapping poor old people into taking into their crappy deals.

A shittier version of Verizon.
John: Hey I just subscribed to Spectrum today!
Nick: Are you stupid? You’re getting scammed, Verizon is where its at.
