What is FT IR? - Northwestern University
www.nuance.northwestern.eduInfrared (IR) spectroscopy is a chemical analytical technique, which measures the infrared intensity versus wavelength (wavenumber) of light. Based upon the wavenumber, infrared light can be categorized as far infrared (4 ~ 400cm‐1), mid infrared (400 ~ 4,000cm‐1) and near
The Fundamentals of Infrared Spectroscopy
www.midac.comMid Infrared 4,500 to 400 cm-1 (2.5 to 50 μm) Far Infrared 400 to 12.5 cm-1 (50 to 800 μm) Using these units, visible light is from 0.36 to 0.75 μm, or 27,778 to 13,333 cm-1. There is a discussion of these units below. In the case of infrared spectroscopy, infrared light passes through a sample and certain
Common Landsat Band Combinations - Middlebury College
geography.middlebury.edu(1.55-1.75 µm, mid-infrared) This band is very sensitive to moisture and is therefore used to monitor vegetation and soil moisture. It is also good at differentiating between clouds and snow. Band 6 (10.40-12.50 µm, thermal infrared) This is a thermal band, which means it can be used to measure surface temperature.
