Interpretation Introduction
Interpretation:
The structure of the fragment ions of
Concept introduction:
Mass spectrometry is a technique used for measuring the masses of atoms and molecules with great accuracy.
In a mass spectrometer, the vapor of an organic compound is bombarded with a beam of high energy electrons that makes the neutral molecule loose an electron and get converted to a radical cation, known as molecular ion.
