Carbonaceous Solid Materials: From Laboratory to Space

We present here an updated review of laboratory results obtained from different carbonaceous materials in grain and molecular forms. Temperature behaviour of bands falling between 3 µm and 13 µm is reported for some PAHs. FIR spectra are measured for ten different solids. Finally, we have also identified several IR space sources which can be studied by means of ISO instruments to contribute a possible clarification on UIBs.
