Abstract
The energy dependence of the vibrational branching ratio for exciting one q
uantum of bending is determined for CO2 4 sigma (-1)(g) photoionization. Th
is nominally forbidden transition becomes allowed for a photoionization tra
nsition as a result of instantaneous symmetry breaking due to zero point mo
tion, and is strongly enhanced by a continuum shape resonance. (C) 2001 Ame
