Abstract
It is shown that the direction of the photoelectron recoil momentum transferred to the photoion influences molecular photoionization dynamics, resulting in the appearance of a specific mode–channel interdependence. We disclose the interdependence and the interplay of the core-hole- and photoelectron-induced recoil effects by passing to normal mass-dependent modes in both coordinate and momentum spaces. As an example, the vibrational structure of the photoelectron line of is investigated in detail. The intensity of bending and symmetric and asymmetric stretching vibrational and rotational excitations is found to differ substantially in the and photoionization channels.
