Two-dimensional versions of this technique, which include NOESY and COSY, use variable pulses to detect interactions, and all modern versions of this technique use a Fast Fourier Transform to obtain information from free induction decay. Relying on the Larmor precession, this technique was developed by Felix Bloch and Edward Purcell, who discovered that atoms will resonate at different frequencies depending on their chemical environment. For 10 points, name this type of spectroscopy that applies

Relying on the Larmor precession, this technique was developed by Felix Bloch and Edward Purcell, who discovered that atoms will resonate at different frequencies depending on their chemical environment. For 10 points, name this type of spectroscopy that applies a strong magnetic field to a sample in order to determine its structure, the basis of MRI.
