Principle of Ultraviolet-Visible Absorption

Ultraviolet-Visible (UV-Vis) Spectroscopy – Principle


Introduction

In our discussion in “Introduction to the Electromagnetic Spectrum and Spectroscopy” we have discussed the different wavelengths for ultraviolet and visible lights which range from 10 nm to 400nm and 400nm to 780 nm respectively. The following chapter discusses to a greater extent the principles involved in the utility of ultraviolet-visible spectroscopy (UV-Vis) and the Beer-Lambert law which is useful in quantitative analysis of sample.
