Diffuse reflectance spectroscopy

Diffuse reflectance spectroscopy (DRS) is a technique used to analyze the optical properties of materials by measuring the light that is scattered from a sample. This method is particularly useful for studying opaque or semi-opaque samples, where traditional transmission spectroscopy would not be feasible due to light absorption or scattering. ### Key Concepts: 1. **Theory**: When light is incident on a sample, it can be absorbed, reflected, or transmitted.
