Abstract
The rotationally resolved A (2)Pi (u) <-- X (2)<Pi>(g) electronic origin ba nd spectrum of tetraacetylene cation (HC8H+) and its deuterated derivative (DC8D+) has been recorded in the gas phase, applying both frequency modulat ion spectroscopy in a liquid nitrogen cooled hollow cathode discharge and c avity ringdown spectroscopy in a supersonic planar plasma. The combined ana lysis of the rotational structure yields accurate molecular constants for t he ground and electronically excited states as well as information on the m olecular geometry.
