TL;DR: In this article, two prototype experiments on a fast motional nitroxide spectrum are described, based on detection of the Han echo and may be used for discriminating the homogeneous broadening of an inhomogeneous spectrum (and/or the echo envelope modulation).
Abstract: New Fourier transform ESR techniques, which permit rapid data acquisition of ESR spectra, now allow one to perform a variety of two‐dimensional ESR experiments. Two prototype experiments on a fast motional nitroxide spectrum are described. The first is based upon detection of the Han echo and may be used for discriminating the homogeneous broadening of an inhomogeneous spectrum (and/or the echo envelope modulation). The second is based upon detection of the FID after the three‐pulse Jeener–Ernst sequence, and it leads to cross peaks due to Heisenberg spin exhange among the hyperfine lines.

TL;DR: Fourier transform infrared (FTIR) spectroscopy is one of the most powerful techniques for chemical analysis in recent years, and is making new inroads into several applications in biological analysis, including food as mentioned in this paper.
Abstract: Fourier transform infrared (FTIR) spectroscopy is considered to be one of the most powerful techniques for chemical analysis in recent years, and is making new inroads into several applications in biological analysis, including food. Fourier transformation (FT) is a mathematical procedure that is applied to the interferograms to obtain the spectrum. Essentially, FT breaks down the interferogram provided by the interferometer into sine waves for each wavelength in the light. These sine waves are arranged over the wavelength to produce the conventional spectrum. Many different types of materials and components are available for FTIR construction. The important components of an FTIR spectrometer are the interferometer, source, beam splitter, detector, and laser. One of the most important components of interferometer is the moving mirror that is required to control its position precisely in order to obtain an accurate measurement of spectra. The function of the detector is to transduce the light intensity received by it to electrical signal. Two most commonly used detectors in both FT-near-infrared (FT-NIR) and FT-mid-infrared (FT-MIR) instruments are the deuterated triglycine sulfate (DTGS), detectors and the mercury cadmium telluride (MCT) detectors.
