Dear Community,
I'm looking for the information on absorption spectrum of gaseous methane CH4 in UV range from 100 to 300 nm, especially around 190 and 260 nm.
If anyone have reliable information, I will appreciate it if you could share it.
Please look at The Absorption Spectra of Methane, Carbon Dioxide, Water Vapor, and Ethylene in the Vacuum Ultraviolet
