Scientific paper

A method to estimate the vibrational distributions for N2 in the ground state by using the intensities of allowed transitions, excited by direct particle impact, is developed. The method is tested on a rather limited amount of data, but the results seem to be reasonable and indicate that 10 percent of the particle energy is stored as vibrational energy by N2 molecules, and that the vibrational temperature is increased more than 1000 K relative to the kinetic temperature on the dayside.
