Abstract

Based on rotationally resolved sub‐Doppler spectroscopy and optical–optical double resonance (OODR) experiments on cold Na₃ molecules in a collimated supersonic argon beam seeded with sodium, 51 rotational transitions selectively excited by OODR in the complex electronic A ²A₂←X ²B₂ system of Na₃ could be assigned unambigiously. Accurate values of the rotational constants and the molecular geometrical parameters have been derived from these measurements.
