Diffuse reflectance infrared fourier transform
Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) is an infrared spectroscopy technique used on powder samples with no preparation. The sample is added to a sample cup and the data...
Snapshot hyperspectral imaging
Snapshot (or "non-scanning") hyperspectral imaging is a method of capturing hyperspectral images during a single integration time of a detector array, so that no scanning is involved. The lack of movi...
Thermal infrared spectroscopy
Thermal infrared spectroscopy (TIR spectroscopy) is the subset of infrared spectroscopy that deals with radiation emitted in the infrared part of the electromagnetic spectrum. The emitted infrared ra...

Global-warming potential
Global-warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the a...
Vibrational circular dichroism
Vibrational circular dichroism (VCD) is a spectroscopic technique which detects differences in attenuation of left and right circularly polarized light passing through a sample. It is the extension of...
