Determining Absorbance in IR Spectroscopy

A quantitative analysis based on the absorption of infrared radiation, although important, is less frequently encountered than those for UV/Vis absorption. One reason is the difficulty in establishing a 100% T (A = 0) baseline as the optical properties of … Continue reading

Transmittance

As light passes through a sample, its power decreases as some of it is absorbed. This attenuation of radiation is described quantitatively T = PT/Po where T is transmittance and PT and Po are, respectively, the source radiation’s power exiting the sample and … Continue reading
