PPT-Nuclear Magnetic Resonance Spectroscopy

Intro to NMR Spectroscopy Nuclear Magnetic Resonance NMR spectroscopy provides structural information about organic compounds and biomolecules NMR involves an interaction between electromagnetic radiation . In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Eluci. dation .

Peaks are often split into multiple peaks due to interactions between nonequivalent protons on adjacent carbons, called spin-spin splitting (multiplicity or coupling pattern). Electron can behave like a tiny bar magnet.. Atomic nucleus can spin and behave as a tiny bar magnet. These . spinning nuclei generate tiny magnetic . fields. Any nucleus will spin (odd mass or odd atomic number. Mass Spectrometry . Carbon-13 NMR. Proton NMR. Chromatography . 1. Infrared Spectroscopy. Absorption of infrared radiation causes bonds to vibrate. Different bonds absorb different wavelengths. These can be identified using the table on the data sheet. . Fall 2017.

It is not possible to see the internal organs and structure of the human body directly to locate the infection or illness . Magnetic resonance imaging (MRI) is a spectroscopic imaging technique used in medical setting to produce image of the internal structure of the human body. The scan uses a strong magnetic field and radio waves to generate images of internal parts ( cells, tissues , organs ) of the body that can't be seen as well with X-rays , CT scans or ultrasounds . For example , it can help doctors to see inside joints , cartilage , ligaments , muscles and tendons , which make it helpful for detecting various sports injuries. It is also used to examine internal body structures and diagnose a variety of disorders , such as strokes, tumors , aneurysms , spinal cord injuries , multiple sclerosis and eye or inner ear problems. It is also widely used in research to measure brain structure and their function.. Spectroscopy. Learning Module #1. - The Electromagnetic Spectrum and Radiation.
