Abstract

Recently the suggestion was made that it ought to be possible to make precision isotope ratio measurements (accuracy ≤0.1%) of light elements (H, B, C, N, O) using quantum counting techniques in conjunction with vibrational Raman scattering from high intensity laser beams. Such a method could well have significant advantages over standard mass spectrometry, especially in applications involving the isotopic assay of hundreds of samples, possibly of very small size, as occurs, for example, in studies of fertilizer transport in soils. Similar remarks apply to isotope assays necessary in a number of other physical, chemical, and biological studies.
