NUCLEAR MOTION, SYMMETRY BREAKING AND DISSOCIATION DYNAMICS OF CORE-EXCITED POLYATOMIC MOLECULES

Abstract

Recent studies on nuclear dynamics of core-excited and Auger final states are reviewed. Emphasis is given to the nuclear motion of the core-excited states and its influence to the subsequent decay and fragmentation processes. As specific examples we discuss two-dimensional nuclear motion caused by the O 1s → 2b2 excitation in H 2 O and by the C 1s → 2πu excitation in CO 2, as well as out-of-plane motion caused by B [Formula: see text] excitation and asymmetric stretching motion caused by the F 1s ionization in BF 3.
