Using Punnett Squares to Facilitate Students' Understanding of Isotopic Distributions in Mass Spectrometry
Sein, Lawrence T., Jr.
Journal of Chemical Education, v83 n2 p228 Feb 2006
The isotopic distribution in mass spectroscopy is described for identifying pure compounds, being able to distinguish molecular fragments by masses. Punnett squares are familiar, easy to compute, and often graphical which makes helpful to students and the relative distribution of isotopic combination is easily generated for even isotopic distribution can be correlated with the peak heights.
