Abstract
THE combination of a two-beam interferometer and Fourier transformation has a great advantage over conventional spectrometers in the effective use of available energy1,2. Further, when the interferometer is of a type which has circular symmetry like Michelson's, there is another gain3 giving the Michelson–Fourier combination an effective luminosity that is the highest of all known spectroscopic systems4. It is most advantageously used in wave-length regions where the limit to the spectroscopic resolution obtainable in a given time of observation is set by detector noise. So in the infra-red region, considerable improvement in spectra over those given by conventional methods is to be expected. This has been realized in practice in the very near infra-red5 and in the far infra-red6,7. This communication describes its application in the 2–12µ region, where many molecular vibrational bands are found.
