Raman spectra of nitrogen-containing organic compounds obtained in high altitude sites using a portable spectrometer: Possible application for remote robotic Titan studies
2010
Abstract
Well-resolved Raman spectra of examples of nitrogen-containing compounds were detected using a portable Raman instrument outdoors at a low temperature of -15 degrees C at an altitude of 2860 m (Pitztall, Austria). Solid forms of formamide, urea, 3-methylpyridine, aniline, indene, 1-(2-aminoethyl)piperazine, benzofuran and indoline were detected unambiguously under field high-mountain conditions.
The results obtained demonstrate the possibility of applying a miniaturised Raman spectrometer as key instrument for investigating the presence of nitrogen-containing organic compounds and biomolecules under low temperature field conditions.
