Abstract

Fourier-transform infrared (FTIR) spectra can show artifacts, for example, in the vicinity of the overtone when light is doubly modulated. Technical approaches, i.e., modifications to the spectrometer setup, have been devised in order to reduce those artifacts. Elimination of the artifacts was achieved only partly but at the expense of a loss of intensity or an increase in the noise level. We devised a computational demodulation scheme that is capable of almost fully reducing the artifacts with neither a loss of spectroscopic information nor an increase in the noise level. This has been demonstrated for the FTIR absorption spectra in the overtone regions of HCl(g) and CH4(g).

Fig. 1. Proposed modifications for a FTIR spectrometer containing a source (A), reflection optics (spherical mirror B, parabolic mirrors C1 and C2, and elliptic mirrors C3), filters and apertures (D), Michelson-type interferometer (E), sample cell (F), main detector (G), secondary detectors (H), reference laser (I), and its detector (J).
Fig. 2.
Fig. 2. Method for generating I corr for compensation used in Eq. (2).
Fig. 3.
Fig. 3. First overtone of HCl (5400 to 5830    cm 1 , resolution 0.5    cm 1 ) with the double-modulation artifacts associated with the fundamental of HCl. The original spectrum (upper trace) was compensated (lower trace) with a single iteration using Eq. (2) and γ 1 = 0.004 . The correction interferogram I corr was arranged as shown in Fig. 2.
Fig. 4.
Fig. 4. Simulated spectra of HCl(g). (a)  A 10 unperturbed obtained with τ R , s = 1 and τ R , d = 0 that is without double modulation (after [23,24]). The spectra were adjusted such as to match the absorbance values of the experiment for better comparability. (b)  A 10 perturbed obtained with τ R , s = 0.996 and τ R , d = 0.004 , which introduces the artifacts caused by double modulation visible above 5800    cm 1 . (c)  A 10 compensated obtained from τ R , s = 0.996 and τ R , d = 0.004 with the compensation parameter γ 1 = 0.004 / 0.996 . This demodulation eliminates the artifacts above 5800    cm 1 completely.
Fig. 5.
Fig. 5. Percentage change of selected rotational lines of HCl [ R ( 2 ) to R ( 6 ) ] when applying the compensation scheme with the compensation coefficient γ between 0 and 0.01. The change of the fundamentals is shown in (a) and the first overtone in (b). The respective artifacts are shown in (c). The horizontal line at 100 % indicates the values of γ , at which the selected artifacts are compensated completely.
Fig. 6.
Fig. 6. P 4 -tetradecad band of CH 4 (5800 to 6150    cm 1 , resolution 0.5    cm 1 ) and double-modulation artifacts of the P 2 -pentad band. The original spectrum (upper trace) was compensated (lower trace) with a single iteration using Eq. (2) and γ = 0.004 . The correction interference function I corr was arranged as shown in Fig. 2. The spectroscopic data and the assignment of the CH 4 bands were taken from Niederer [25] and Ulenikov et al. [26]. R ( 2 ) marks a rotational line in the R -branch of the respective absorption band.
Fig. 7.
Fig. 7. Percentage change of the absorbance for selected rotational lines of CH 4 when applying the demodulation scheme with the compensation coefficient γ 1 between 0 and 0.01. The change of the selected P 2 -pentad bands is shown in (a) and the change of the absorbances of the P 4 -tetradecad band in (b). The respective artifacts from the P 2 -pentad can be seen in (c). The horizontal line at 100 % indicates the values of γ 1 , at which the selected artifacts are compensated completely.
Fig. 8.
Fig. 8. Difference spectrum Δ A 10 diff = A 10 comp A 10 exp [Fig. 6, lower trace minus upper trace] from 800 to 12,000    cm 1 of CH 4 (resolution 0.5    cm 1 ). Negative bands are compensations of the artifacts, positive signals lead of a signal raise of “true” signals. The following artifacts were found: P 1 -dyad artifact at 2550    cm 1 , P 2 -pentad artifact at 6000    cm 1 , P 3 -octad artifact at 8600    cm 1 , and the P 4 -tetradecad artifact at 11,750    cm 1 . The spectral data and the assignment of the CH 4 bands were taken from Niederer [25] and Ulenikov et al. [26].
Fig. 9.
Fig. 9. Cross section of a parabolic mirror (C1 or C2) having two conic holes, see Fig. 1, one parallel to the focused beam and one parallel to the collimated beam. This is used to measure the reflection interference signal and prevent further reflections toward the interferometer [19,20].
