Review:
Fourier Transform Infrared Spectroscopy
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Fourier-Transform Infrared Spectroscopy (FTIR) is an analytical technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. It works by passing infrared radiation through a sample and measuring how much radiation is absorbed at different wavelengths. The infrared spectrum generated provides detailed information about the molecular composition, structure, and bonding within the sample, making FTIR a powerful tool in chemistry, material science, environmental analysis, and quality control.
