Nuclear Magnetic Resonance: Principles and Applications of NMR

Nuclear Magnetic Resonance: Principles and Applications of NMR // In this video, we learn about the basic principles of nuclear magnetic resonance (NMR), we learn about the NMR and MRI magnets and we also get a glimpse into the many possible applications of NMR. The NMR magnet can be used for solution-state NMR experiments (where the sample is in liquid form, placed in an NMR tube) and for solid-state NMR experiments (where the sample is a powder, placed in an NMR rotor), both of them being valuable tools in scientific research. The basic principles of NMR rely on exploring the nuclear spins and their behavior in an external magnetic field. By using radio-frequency pulse, we can manipulate these spins and record different NMR experiments that reveal important structural information about the sample that we investigate. This information is revealed through NMR spectra, which are the representation of the NMR signal in the frequency domain. By analyzing the NMR chemical shifts, which are very sensitive probes to local structure, we can infer information about the structure of a molecule or a crystal. NMR is a very versatile tool with many possible applications, including some application of NMR in cultural heritage.

I'm a scientist and a Sci-Fi/Fantasy writer. When I was working in academia, in my research, I use different scientific methods to study precious objects of cultural heritage, such as ancient mummies and bones, paintings, and violins. One of my scientific research projects involves developing a scientific method to identify fake paintings. I love our world heritage and I want to share with the world fascinating cultural heritage stories through my videos, my blog, and my novels. #CulturalHeritage #HeritageScience #Science #scienceeducation Music - "Up Kilkenny (Instrumental version)" by Josh Woodward.
