Since the introduction of FT-IR spectroscopy, it is very well accepted by the research community that a spectrometer based on a vacuum optics bench provides IR spectra which are free of residual H2O- and CO2- absorption bands. Such residual absorptions of the laboratory room air are typically visible under purge conditions and may mask weak spectral...

In the 70s of the last century first attempts to make use of the advantage of bright and highly collimated e-synchrotron radiation not only in the short wavelength range (UV, X-Ray) but also in the long wavelength range (FIR, typically 400 to 10cm-1) failed. The theoretically expected advantage of the synchrotron radiation as bright but expensive IR sources...
