Figure 4From: Electron excitation and energy transfer rates for H2O in the upper atmosphereElectron energy transfer rates for higher energy electronic states. Plot of the present electron energy transfer rates (eVcm3s-1), as a function of electron temperature (K), for more of the excited electronic states in H2O (states 10–18 of table 1 and as labelled in the plot). Also shown is the sum of the energy transfer rates for all 25 electronic states.Back to article page
