[FT-IR] Fourier Transform Infrared Spectroscopy
Infrared spectroscopy is a method to obtain information on molecular structure by measuring infrared absorption due to molecular vibration.
[O-PTIR] Optical Photothermal Induced Resonance
O-PTIR may be referred to as mIRage (product name).
[Raman] Raman Spectroscopy
Raman spectroscopy is a technique to obtain information about the structure of molecules by using the light scattering phenomenon (Raman effect), in which the number of vibrations of the incident light changes as a result of the interaction between the incident light and the molecule.
