WebSep 12, 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton. WebThere are no absorption cross section measurements in the 200 nm wavelength region for HFC-125. However, considering that this is a saturated hydrocarbon with only fluorine, hydrogen and carbon atoms, the absorption in that wavelength region should be negligible. In general, at those wavelengths the absorp-
