Fourier Transform Infrared Emission Spectroscopy (FT-IRES)... 

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-...

Infrared emission spectroscopy forms a valuable technique that can be plied in situ during the heat treatment. The technique of measurement of discrete vibrational frequencies emitted by thermally excited molecules, known as Fourier transform infrared emission spectroscopy (FTTR ES, or shortly lES) has not been widely used for the study of materials. The major advantages of lES are that the samples are analyzed in situ at increasing temperatures and lES requires no sample treatment other than that the sample should be of submicron particle size. Further, the technique removes the difficulties of heating tiie sample to temperatures where reactions take place with subsequent quenching prior to the measurement, because lES measures the process as it is actually taking place.

In detailed studies of CH3NO2 photodissociation at wavelengths within the tt tt band (193-218 nm), Butler et al. (1983), Lao et al. (1990), and Moss et al. (1992) employed molecular beam translational energy spectroscopy and product emission spectroscopy to demonstrate that two distinct mechanisms were involved in the process (I). The dominant mechanism releases a relatively large fraction of the total available energy to translation with NO2 formed in a vibrationally excited A B2 state which can rapidly dissociate to NO and O. Wade et al. (2006) found similar results when they photolyzed CH3NO2 at 192, 248, and 266 nm and observed the products by time-dependent Fourier transform infrared emission spectroscopy. The primary process (I) was dominant with A B2 NO2 formation. 

Wade et al. (2006) studied the photodecomposition of CCI3NO2 (chloropicrin) at 193, 248, and 266 nm using time-dependent Fourier transform infrared emission spectroscopy. At 266 nm the major photodissociation channel formed CCI3 + N02(A B2), analogous to channel (I) in the photolysis of the other nitroalkanes. Phosgene [C1C(0)C1] was not detectable in this work, and the authors suggest that its production and that of CINO that has been observed in environmental chambers (Moilanen et al., 1978) and cryogenic matrices (Wade et al., 2002), is likely the result of secondary reactions.

NMR) [24], and Fourier transform-infrared (FT-IR) spectroscopy [25] are commonly applied methods. Analysis using mass spectrometric (MS) techniques has been achieved with gas chromatography-mass spectrometry (GC-MS), with chemical ionisation (Cl) often more informative than conventional electron impact (El) ionisation [26]. For the qualitative and quantitative characterisation of silicone polyether copolymers in particular, SEC, NMR, and FT-IR have also been demonstrated as useful and informative methods [22] and the application of high-temperature GC and inductively coupled plasma-atomic emission spectroscopy (ICP-AES) is also described [5]. 

Spectroscopic techniques may provide the least ambiguous methods for verification of actual sorption mechanisms. Zeltner et al. (Chapter 8) have applied FTIR (Fourier Transform Infrared) spectroscopy and microcalorimetric titrations in a study of the adsorption of salicylic acid by goethite these techniques provide new information on the structure of organic acid complexes formed at the goethite-water interface. Ambe et al. (Chapter 19) present the results of an emission Mossbauer spectroscopic study of sorbed Co(II) and Sb(V). Although Mossbauer spectroscopy can only be used for a few chemical elements, the technique provides detailed information about the molecular bonding of sorbed species and may be used to differentiate between adsorption and surface precipitation. 

The characterization of graphene often involves several techniques in conjunction in order to build up a complete picture of the material. The techniques typically include electron microscopy, Raman spectroscopy, X-ray photo-emission spectroscopy (XPS), Fourier-transform infrared spectroscopy (FTIR) and thermal-gravimetric analysis (TGA).
