Nuclear Magnetic Resonance spectroscopy
... A pulse of electromagnetic radiation covering the entire spectrum under scrutiny (NMR, UV, IR) is used to obtain the whole spectrum instantly. The pulse may be applied multiple times and the results accumulated and averaged, which provides for very high sensitivity. The signal measured is actually t ...
