Absorption coefficient α calculation from UV-Vis absorbance data in origin
https://www.seevid.ir/fa/w/9UYAVZnJt9k what is absorption coefficient α
https://www.seevid.ir/fa/w/9UYAVZnJt9k how to calculate the absorption coefficient α from UV-Vis absorbance data in origin
In this YouTube video, we will learn how to calculate the absorption coefficient (α) from UV-Vis absorbance data using Origin software. The absorption coefficient is a crucial parameter that describes the ability of a material to absorb light. In this tutorial, we will demonstrate how to import UV-Vis data into Origin, plot the absorbance spectrum, and calculate the absorption coefficient using the Tauc plot method. We will also explain how to adjust the plot settings and customize the plot appearance to make it more visually appealing. By the end of this video, you will have a better understanding of how to use Origin software to analyze UV-Vis absorption data and calculate the absorption coefficient, which is essential for many scientific and engineering applications.

The absorption coefficient describes how much light of a given color is absorbed by a material of a given thickness. The absorption coefficient is often represented by the Greek letter alpha. It has units of 1/cm (1/length), because it describes the amount of light absorbed per thickness of material.
