WebbThe shape of lines in a nuclear magnetic resonance (NMR) spectrum is determined by the process of free induction decay. This decay is approximately exponential, so the line shape is Lorentzian. [10] This follows because the Fourier transform of an exponential function in the time domain is a Lorentzian in the frequency domain.

WebbX-ray crystallography is the experimental science determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, a crystallographer can produce a three-dimensional picture of the … WebbThe shape of lines in a nuclear magnetic resonance (NMR) spectrum is determined by the process of free induction decay.
