Question
Chapter 18, Problem 18.2QAP
Interpretation Introduction
Interpretation:
The reason for the increase in the ratio of anti-Stokes to Stokes intensities with sample temperature is to be stated.
Concept introduction:
Raman spectrum consist two frequency emissions. The emission with lower frequency is called Stokes scattering (intensity or line) and with higher frequency is called anti-Stokes scattering (intensity or line).
