 Diffuse reflectance infrared Fourier transform spectroscopy

Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) is an analytical technique used to obtain the infrared spectrum of solid and powdered samples. It is particularly useful for materials that are difficult to analyze in traditional transmission mode, such as powders, solid materials, and heterogeneous samples. ### Key Features of DRIFTS: 1. **Principle of Operation**: DRIFTS involves the interaction of infrared radiation with the sample surface.
