Elemental Composition Determinations Using the Abundant Isotope
Journal of the American Society for Mass Spectrometry, 2019Elemental compositions are commonly determined from the exact m/z of the monoisotopic peak, which is often the lightest isotope. However, the lightest isotope peak is often weak or absent and the monoisotopic peak can be difficult to identify for organometallics, polyhalogenated compounds, or large molecules.

Isotopic Abundances in RGB- and AGB-Stars
2006Asymptotic Giant Branch stars contribute significantly to the chemical evolution of their host galaxies. All stars with a main-sequence mass = 8M ? will return eventually 30-80% of their mass to the interstellar medium. In parallel to the He-burning phase, which follows the original main sequence H-burning, AGB stars are known to produce heavy elements.

Isotopic Abundances in Interstellar Clouds
1977The observation of microwave spectra of molecules in interstellar clouds allows separation and detection of the lines of isotopes of many of the more common elements. Comparison of intensities of isotopic lines shows that the relative isotopic abundances for C, O, S, N, and Si are generally rather similar to those found on Earth.
