Nano-world: from molecules to living cells, chemical imaging, microscopes, nanoscopes, infrared and terahertz waves

(Nano-Welt: von Molekülen zu lebenden Zellen, chemische Bildgebung, Mikroskope, Nanoskope, Infrarot und Terahertz Wellen)
 

Terahertz (THz) and Infrared (IR) research
KAO airplane tail does not fit in the hangar NASA mission (Sept. 1993: photos) on the Kuiper Airborne Observatory ( KAO), Ames, California. Observation flights in astronomy: study fine-structure emission lines of N+ at 205 µm (1.46 THz) in objects DR21, S106, W49. Further reading - references on N+: J. M. Brown et al., ApJ 428, L37 (1994): The fine-structure intervals of (N-14)+ by far-infrared laser magnetic resonance, COBE FIRAS full sky map of N+ at 205 µm (1.46 THz, see Fig. 1 of the publication).
