Jupiter's atmosphere is mostly ... features in Jupiter's visible spectrum, to calculate the abundance of these gases above Jupiter’s cloud tops. Methane's absorption at 619 nm serves as a ...

It provides critical insights into the molecular structure and composition of materials by measuring their infrared absorption spectra. This article delves into the definition, principle of operation, ...

The predicted intensity of this spectrum is so low that a path of the order of 10 km. at atmospheric pressure is required to obtain it in absorption 1,2.
