What are the limitations of UV-Visible spectroscopy?

In recent years, UV-visible spectroscopy has become an increasingly popular technique in various industries, including chemistry, biology, and materials science. As researchers and scientists continue to explore the potential of this technique, understanding its fundamentals has become essential for making informed decisions and achieving accurate results. In this article, we'll delve into the world of UV-visible spectroscopy, exploring its principles, applications, and limitations.

UV spectroscopy involves measuring the absorption of light in the ultraviolet range (200-400 nm), while visible spectroscopy measures the absorption of light in the visible range (400-800 nm). Both techniques are used to analyze the molecular structure of a sample, but UV spectroscopy is often used for detecting functional groups and visible spectroscopy for identifying molecular structures.

However, there are also realistic risks associated with UV-visible spectroscopy, including:
