Micro-FTIR and FTIR spectroscopy is useful for the study of degradation forms of cultural heritage. In particular it permits to identify the degradation phases and to establish the structural relation...
Within the framework of the NDSC (Network for the Detection of Stratospheric Change) ground-based FTIR solar absorption spectra have been routinely recorded at Izaña Observatory (28° N, 16° W)...
The sensitivity of ground-based instruments measuring in the infrared with respect to tropospheric water vapour content is generally limited to the lower and middle troposphere. The large vertical gra...
Lawsonite single crystals were investigated by polarized FfIR spectroscopy at wave-numbers between 8000 and 1000 cm-1 and temperatures between 82 and 325 K.This temperature range contains three lawson...
In the critical comment byNathan (1996), the author essentially claims that the samples used in our study (Regnier et al. 1994) werenot very appropriate to dem-onstrate the absence of C03P-. Furthermo...
The carbonate substitution in apatite continues to pro-voke controversies. In a recent paper, Regnier etal. (1994) challenged the existence of the hypothetical C03P- ion in carbonate-fluorapatite (fra...
