Microwave Resonance Lines of ¹⁶O₂ in Its Electronic Ground State (X ³Σ_g ^-)

Abstract

Low intensity absorption lines of 16 O 2 , in v =0 and v =1 states, are observed in the 119 and 60 GHz regions. New sets of values for the molecular parameters, including λ DD which has not been observed yet, are obtained.
