WebThe mass spectrum. A mass spectrum is usually presented as a vertical bar graph, in which each bar represents an ion having a particular m / z ratio and the length of bar represents the relative abundance of that ion in the sample. The most intense ion is assigned an abundance of 100, and it is referred as the base peak. Webmass spectrum is relative intensity.Therefore, the height of each of the peaks will correspond to the relative abundance of each isotope in the sample. As an example, examine Figure 1.This is a mass spectrum of a natural sample of atomic carbon. 12 C, with a natural abundance of 98.89%, naturally has a very high peak. 13

WebC=O has a larger dipole moment than C=C, meaning C=O has a stronger bond strength. This is because of the difference in electronegativity values of C and O. As you already know, a greater mass of the atoms of a bond means a lower frequency. But C=O has a greater bond strength, which apparently compensates for the difference in mass.
