From: Electron excitation and energy transfer rates for H2O in the upper atmosphere
Excitation Rates for higher energy transitions. Present electron impact excitation rates (10-7 /s), as a function of altitude (km), for the remaining excited electronic states pertaining to this study. These remaining states are labelled 9 through 27, where 9 refers to the A1 state, 27 refers to the final 1A1 state and the rest are in the same order as listed in table 1.
