Chapter 21, Problem 21.6QAP

Interpretation Introduction

Interpretation:

The comparison of EELS to conventional IR and Raman spectroscopy, the advantage and limitation of EELS.

Concept introduction:

In an electron energy-loss spectroscopy (EELS), a low energy beam of electron strikes the surface of the sample and excites vibrations. In infrared spectroscopy, the measurement of transmitted infrared radiations is done after they passed through the sample, and in Raman spectroscopy, the scattered radiations in the visible region are measured after they are passed through the sample.
