Methylpropenal mass spec
Web2 jun. 2024 · 1 Answer Sorted by: 4 This spectrum is recorded using electron impact. That means that the molecule is positively charged by losing one electron. Since that is a very unstable structure, the molecule … Webatomic mass of 12.01115 Da, hydrogen is 1.00797 Da, and so on. The average mass of the molecular ion of a chemical compound is also the mass that appears on the bottle. How-ever, in a stick representation of a mass spectrum, there is no ion signal at the average mass. Instead, signals appear for ions of various isotopic compositions.
