What Is Magnetic Resonance Spectroscopy?

Magnetic resonance spectroscopy is a technique used to investigate and identify chemicals. It depends upon the fact that some nuclei react to the presence of a magnetic field in a recognizable way.

  1. Function

    • Magnetic resonance spectroscopy is used to investigate chemical composition in living tissue and chemical samples.

    Research Use

    • Scientists can use magnetic resonance spectroscopy to find out more about the chemicals that are present in a sample and the shape and composition of particular chemicals.

    Medical Use

    • Magnetic resonance spectroscopy is a noninvasive technique for studying tissue in patients. It is commonly used to diagnose disorders of the central nervous system.

    How It Works

    • Nuclei with an odd atomic number possess a characteristic known as spin. Magnetic fields can affect this spin. Electrons shield the nucleus from magnetism, so the response will depend in part upon the chemical environment of the nucleus. The reaction of the nucleus therefore provides information about the structure of the chemical that contains it.

    Procedure

    • The sample is placed within a magnetic field. A second, oscillating magnetic field, known as the RF pulse, is then applied, and the response of the sample nuclei is observed.
