Predicting spin-spin coupling patterns in NMR spectra
... split each line of the doublet into a triplet (2x2x½ + 1 = 3). The CH2F protons therefore give rise to a doublet of triplets in the spectrum. The CH2 protons will be coupled to the CH 2F protons, the F nucleus, and the CH3 protons. The peak will be split into 4 by the CH 3 protons (2x3x½ + 1 = 4); ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
