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 ...

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 ...

Firstly, the absorption spectra of many gases in the conventional ... Secondly, because these pollutants are volatile in the atmosphere, they are difficult to trace. The new laser technology ...
