FTIR Spectrum Analysis--Meaning and Application of Each Peak
2024年6月16日 · Peak interpretation in FTIR analysis involves understanding and explaining the various peaks on the spectrum. These peaks represent the sample's absorption of infrared light, with each peak corresponding to a specific chemical bond or functional group absorbing infrared light at a particular wavelength.
13.1.16: How to Interpret An Infrared Spectrum
Infrared spectroscopy is the study of the interaction of infrared light with matter. The fundamental measurement obtained in infrared spectroscopy is an infrared spectrum, which is a plot of measured infrared intensity versus wavelength (or frequency) of light.
