Infrared spectral atlases of the sun from noao

We have prepared a series of four solar spectral atlases. The atlases illustrate the disk center photospheric spectrum from 0.7 to 22 mu m and the sunspot umbral spectrum from 1.2 to 21 mu m. The spectra were observed at high resolution (lambda/Delta/lambda similar to 300,000) with the Fourier transform spectrometer (FTS) at the McMath-Pierce solar telescope on Kitt Peak. When possible, solar observations at different air masses and on different days have allowed the less opaque telluric lines to be effectively removed from the program spectrum. The solar lines have been identified by searching the literature on atomic and molecular laboratory spectroscopy and when necessary by additional laboratory spectroscopy. Many new identifications have been made, including numerous SiO and hot water lines in the sunspot spectrum.
