Fourier Transform Infrared Emission Spectroscopy FT-IRES

Fourier Transform Infrared Emission Spectroscopy (FT-IRES) 

In an interesting article by Sullivan et al. [182], different IR spectroscopic techniques (except photoacoustic IR spectroscopy) were compared (cf. Table 3). 

There was also described and discussed the relatively new Fourier transform infrared emission spectroscopy (IRES), its principle, an appropriate FT-IRES setup and applications. FT-IRES is unique in that it does not require an external radiation source, because the sample itself is the source. The radiation emitted from the sample is collected and sent to the detector. The ratio of the sample signal to that from a black body source represents the spectrum. However, appli-
