Resumen

Las proporciones de isótopos de osmio en los sedimentos marinos pueden estimar el tamaño del impactador. Sin embargo, la fracción de material del impactador que se disuelve en el agua de mar es pequeña e impredecible, lo que requiere una reevaluación de las suposiciones anteriores.

Mass Spectrometry: Isotope Effect

Most elements exist in nature as a mixture of isotopes. The isotopes differ in weight due to their respective number of neutrons. The molecular weight of a molecule is different depending on the specific isotope of its elements involved. As a result, the mass spectrum of the molecule exhibits peaks from the same fragment at multiple positions. The positions of these mass signals depend on the mass differences between isotopes. Furthermore, the intensity of these signals is dependent on the...
