Cavity ring-down spectroscopy is used to record an absorption spectrum of H2 O water vapor in the 16 570–17 120 cm 1 region. In the spectrum, 596 lines are identified as belonging to H2 O, of which 375 lines are assigned by comparing to newly calculated theoretical lines. The spectrum covers the entire 5m polyad and two new vibrational band origins, (321) at 16775.381 cm 1 and (401) at 16854.99...

During the second flight of the ORFEUSSPAS mission in November/December 1996, the Echelle spectrometer was used extensively by the Principal and Guest Investigator teams as one of the two focal plane instruments of the ORFEUS telescope. The spectrum of HD93521 was obtained during this mission with a total integration time of 1740 s. This spectrum shows numerous sharp interstellar absorption lin...

The infrared spectrum of sunspots is analyzed in the H-band region (5540–6997 cm 1) with the aid of a new, hot (T 1⁄4 1800 K) laboratory emission spectrum of water covering 4878–7552 cm 1. There are 682 lines in the sunspot spectrum and 5589 lines in the laboratory spectrum assigned quantum numbers corresponding to transitions due to H2O using a combination of previously known experimental ener...

the near field ground motions have a high amplitude pulse like at the beginning of the seismogram which are significantly influenced by the rupture mechanism and direction of rupture propagation. this type of ground motion cause higher demands for engineering structures and its response spectrum is dramatically different than far field spectra. tabriz is one of the ancient cities in azerbaijan ...

Further lines of the anomalous optical absorption spectrum in low metamict zircon have been observed in the infra-red. Low-temperature polarization studies have enabled a clear distinction to be made between lines due to the anomalous spectrum and those due to the normal spectrum of U ~in zircon. Magnetic circular dichroism measurements showed, for the anomalous spectrum, only contributions due...
