چکیده

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 energy levels for water and variational line lists. A further 201 unassigned lines common to both spectra can also be associated with water. Subject headings: infrared: solar system — infrared: stars — molecular data — sunspots On-line material: color figure, machine-readable tables

High-Temperature Rotational Transitions of Water in Sunspot and Laboratory Spectra

Assignments are presented for spectra of hot water obtained in absorption in sunspots (T approximately 3000&deg;C and 750 </= nu; </= 1010 cm-1) and in emission in the laboratory (T approximately 1550&deg;C and 370 </= nu; </= 930 cm-1). These assignments are made using variational nuclear motion calculations based on a high-level ab initio electronic surface, with allowance for both adiabatic ...

Water on the sun: line assignments based on variational calculations.

The infrared spectrum of hot water observed in a sunspot has been assigned. The high temperature of the sunspot (3200 K) gave rise to a highly congested pure rotational spectrum in the 10-micrometer region that involved energy levels at least halfway to dissociation. Traditional spectroscopy, based on perturbation theory, is inadequate for this problem. Instead, accurate variational solutions o...

Determination of Leaf Relative Water Content of Two Genotypes of Sesame Using Visible and Near- Infrared (VIS/NIR) Spectrometry to Detect Drought Stress

Relative water content (RWC) in plants is one of the most important biochemical parameters and its deficiency limits efficiency of photosynthesis and crop productivity. The scientific reports on using spectroscopy in detecting drought stress for sesame plants are very rare. In this study, the possibility of identifying water stress in two sensitive (Naz-Takshakhe) and resistant (Yekta) genotype...
