WebSimply put, as mass of the atoms involved in the bond goes up, the wavenumber goes down. Many inorganics have peaks below 400cm- 1, such as ferrocene, acetylferrocene and cadmium oxide. This necessitates the use of “far-IR” optics. Many forensics users have found far-IR useful in identifying paint chips, due to their inorganic content. WebBoth FTIR spectrometers are equipped with Perkin-Elmer variable angle reflection-absorption attachments. All spectra measured with the IRRAS method were collected as single beam spectra. To improve the signal to noise ratio, 128 scans are recorded, co-added and then averaged. A single beam reflectance spectrum was taken from an aluminium
