The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution.

Webb’s infrared instruments will be capable of detecting the types of molecules in the atmospheres of exoplanets by seeing which elements are absorbing light as the planet passes in front of its star, a scientific technique known as transit spectroscopy.
(NASA’s Webb Telescope to Investigate Mysterious Brown Dwarfs, NASA)
A type of spectroscopy that analyzes the X-rays emitted by a sample after exposure to a focused beam of high energy electromagnetic radiation to determine the atomic composition of a region of a sample.

The Irradiation Shared Resource provides Cancer Center investigators with support in the following areas: cell, tumor, specimen, animal irradiation for studies of radiobiologic mechanisms or to suppress immune responses in experimental animals, as well as to sterilize various cell, vaccine and drug preparations; radiotherapy models development and treatment planning, laser and photodynamic therapy, in vivo imaging, in vivo fluorescent imaging, atomic absorption spectroscopy, DNA damage and other radiation assays, safety training and dosimetry measurements.
(Irradiation Shared Resource, NCI Thesaurus)
Using a technique called pulsed field gradient (PFG) nuclear magnetic resonance (NMR) spectroscopy, which is not readily applied to battery electrode materials, the researchers measured the movement of lithium ions through the oxides, and found that they moved at rates several orders of magnitude higher than typical electrode materials.
