(ASSERT) Collisions of Atmospheric Gas Molecules.

Abstract

The absolute electron-impact optical emission cross sections of numerous vibrational bands of the second positive band system of the nitrogen molecule have been measured for electron impact energy from threshold up to 600 eV. From the optical data the apparent electron-impact excitation cross sections for five vibrational levels of the C3Pi sub u electronic state of the nitrogen molecule have been determined. We have constructed a new apparatus for measuring the electron-impact optical cross sections for infrared emissions using a Fourier Transform spectrometer for optical detection. This apparatus allows us to study many important infrared emissions which could not be detected previously by our photomultiplier optical detection systems.
