Preferred Label : Reflectance or Transmission Spectroscopy;
NCIt related terms : REFLECTANCE SPECTROSCOPY;
NCIt definition : The spectroscopic analysis of light reflected from a polished sample. The peaks of
reflectance/transmittance occur in the same spectral region where the sample absorbs
light. In near infrared (IR) reflectance/transmission spectroscopy (NIRS), the reflectance
signals result from bending and stretching vibrations in molecular bonds between carbon,
nitrogen, hydrogen, and oxygen. (from FRTR Field Sampling and Analysis Technologies
