These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun. \(1\). Line spectra are produced when electrons move from one ...

transitions due to these can be seen in very long absorbing paths such as are present in the atmosphere. This report shows that absorption in the solar spectrum near 4.2µ is due to collision ...

and uses the fact that for medium resolutions there exist spectral regions uncontaminated by atmospheric absorption lines. However, it is also applicable (in a somewhat modified form) to spectra ...
