ABSTRACT. This paper contains the analysis of the A1 of Na2 based on the data obtained from thepolarization labeling spectroscopy experiment on the A' —X' transition. A set of Dunham coefficients is derived, which describes the A state in the wide range of v and J 126) quantum numbers and reproduces the positions of unperturbed rotational lines in the A-X band system towithinO.1 cm'.1. INTRODUCTION.We report' new analysis of the A' state based on the data obtained from polarization labelingspectroscopy (PLS) experiment"2, based on V-type optical—optical double resonance scheme, on the 1 : ' ; band system of sodium dimer. The diatomic alkali molecules, with their simple electronic configuration and main absorption bands conveniently positioned in the visible region, are relatively easy to handle both theoretically and experimentally. Hence they have long been employed for testing quantumchemistry calculations. Modern theoretical methods have a potentiality to predict potential curves andspectroscopic constants with high accuracy'. On the experimental side a huge amount of data have been
