 Fourier-transform infrared spectroscopy

Fourier-transform infrared spectroscopy (FTIR) is an analytical technique used to obtain the infrared spectrum of absorption or emission of a solid, liquid, or gas. It is widely employed in chemistry, material science, and various fields to identify and characterize substances based on their molecular vibrations. ### Key Features of FTIR: 1. **Principle**: FTIR works on the principle that different molecules absorb specific frequencies of infrared light to produce vibrational transitions.
