isotopic abundance उदाहरण वाक्य

उदाहरण वाक्य

1. However, practically all hydrogen bonded to carbon atoms is 1 H in natural isotopic abundance samples, including any 13 C nuclei bonded to H atoms.
2. IUPAC is also known for standardizing the atomic weights of the elements through one of its oldest standing committees, the Commission on Isotopic Abundances and Atomic Weights.
3. Isotopic abundances provide important clues to the date of events that allowed a material to begin accumulating gaseous decay byproducts, or that allowed incident radiation to begin transmuting elements.
4. This allowed them to obtain high-resolution proton spectra in solids . a key step for three-dimensional structure determination of organic and inorganic materials at natural isotopic abundance.
5. The upper mass limit for planethood is roughly 13 times Jupiter's mass for objects with solar-type isotopic abundance, beyond which it achieves conditions suitable for nuclear fusion.
6. By studying the ratio between two isotopes of the same element, we avoid effects involving the overall abundance of the element, which usually swamp the much smaller variations in isotopic abundances.
7. Since coupling between other carbons in natural isotopic abundance samples is negligible, signals in fully proton decoupled 13 C spectra in hydrocarbons and most signals from other organic compounds are single peaks.
8. The intensity of the mass-spectrometry peaks is proportional to the isotopic abundances in the molecular species . 12 C 2 H 1 H 3 can also be observed with molecular weight of 17.
9. As the name implies, the carbonaceous chondrites are rich in carbon, and many have anomalies in the isotopic abundances of H, C, N, and O ( Jessberger, 2000 ).
10. As the name implies, the carbonaceous condrites are rich in carbon, and many have anomalies in the isotopic abundances of H, C, N, and O ( Jessberger, 2000 ).
