WebbNear InfraRed Spectroscopy: Absorption bands in the near infrared (NIR) region (750 - 2500 nm) are weak because they arise from vibrational overtones and combination … WebbData treatment. The UV/Vis spectra collected are taken mainly in the liquid phase (this reflects the nature of the literature the spectra are abstracted from). Consequently the data on the solvent used are included. In some rare cases when data published were obtained in the gas or vapor phases just such spectra were included in the collection.

"WebbIt is a (inverse) function of the amount of absorption and the amount of scatter from the sample. With particles much larger than the wavelength, there is little change in the amount of scatter with wavelength. There is generally a large increase in NIR absorbtion as one moves to longer wavelengths. Tony Davies (Td) " - Nir absorption table
