Abstract

Using the VIPCO technique, we remeasured and completed the breakdown diagram of CCl~4~^+^ up to 21 eV energy. The angle‐resolved data show both orientation and alignment of photoelectrons relative to CX~3~^+^ fragments from photoionization to the low‐lying states of CF~4~^+^ and CCl~4~^+^. The strength of the orientation (forward/backward asymmetry) is surprising in view of the nearly spherical symmetry of the parent molecules, and calls for theoretical explanation. It may indicate that nuclear and electron motion take place on similar time‐scales. Copyright © 2002 John Wiley & Sons, Ltd.

In CCl.,/Ar and Ccl&r discharges the upper state (A 'A) of the 278 nm CC1 emission is populated by excitation of groundstate CCl(X TI) only at low CC& molar fractions. With increasing CCL content dissociative excitation of Ccl, into CCl(A 'A) dominates, while ground-state CC1 becomes increasingly co
