Question
Chapter 7, Problem 133E
Interpretation Introduction
Interpretation:
The location and relative intensities of the various peaks in the PES spectrum of carbon has to be explained.
Concept introduction:
PES Spectrum:
- Photoelectron spectroscopy is a technique which is used to know the electronic structure of atoms and molecules.
- In this technique, the ionization samples are bombard with high-energy radiation like UV or X-rays.
- The PES spectrum is sketched by relative electron count versus electron binding energy.
