PPT-Lecture 37 Nuclear magnetic resonance

Nuclear magnetic resonance The use of NMR in chemical research was pioneered by Herbert S Gutowski of Department of Chemistry University of Illinois who established the relationship between chemical shifts and molecular structures He also discovered spinspin coupling. 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 David .

Important points: force applied AT the natural frequency!. : commonly referred to as NMR,. . is a technique which exploits the magnetic properties of certain nuclei to study physical, chemical, and biological properties of matter.

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.. for. Peanut. - shaped bars. NGC 7582. Alice Quillen. University of Rochester. Motivation.
