Dissociation of Molecules by Slow Electrons

  • Chapter
Electron-Molecule Collisions

Part of the book series: Physics of Atoms and Molecules ((PAMO))

Abstract

At a first glance it might appear unlikely that the nuclei within a molecule can be separated in a collision with such a light particle as an electron. However, according to the Born—Oppenheimer principle, the effective potential controlling the motion of the nuclei is given by the eigenvalues of the electronic Hamiltonian. Thus, a change in the electronic structure of the molecule can have a profound effect on the nuclear motion, and an electronic transition will often be accompanied by vibrational excitation or dissociation of the molecule.

  141. The four poles of a quadrupole mass spectrometer are connected to both AC and DC voltages. The rf voltage, V, and dc voltage, U, are given by V = 7.22mf 2 r 2 0 U = 1.22mf 2 r 2 0, where f is the rf frequency (megacycles/s), m is the mass (amu), and r 0 is the radius tangent to the four poles (cm). For m = 23, f= 1.6 and r 0 = 3, V= 2826 V, and U = 635 V. These are rather large voltages; however, a given Rydberg atom will not see the full voltage and resulting field since the pole voltages alternate plus, minus, plus, minus.
