Abstract
The B-2 A'(1) - X(2)B(2) system of Na-3 has been investigated at rotat ional resolution by using resonant two photon ionization and optical-o ptical double resonance spectroscopy. A number of vibronic bands were assigned and rotationally analyzed. In states which are excited by at least one quantum in the linear distortion mode, the three sodium nucl ei perform a free pseudorotational motion in the moat of a pseudo-Jahn -Teller potential. Structure and dynamics of this floppy molecule are discussed on the basis of the measured rotational and Coriolis couplin g parameters.
