Table 1: Principal IR Absorptions for Certain Functional Groups
WebUnits used in IR spectroscopy The wavelength of light in the IR region varies from about 2.5 to 40 μ where 1 μ= 10-4 cm. Since λ cmν sec-1 = c and E = h ν, then ν= c/ λ; νis proportional to 1/ λ, the general convention in IR is to list frequencies proportional to energy. Frequencies in IR are generally expressed in 1/ λunits; ie cm-1 ... WebThe infrared waves typically have wavelengths between 0.75 and 1000µm. This is 750 nm up. a - The wavelength region from 0.75 to 3µm is known as the near infrared region.
