✦ Synopsis

The dipole moment of NO(B 2I-1) was determined for the first time by high resolution laser-induced fluorescence molecular beam spectroscopy. Specific values obtained are as follows: /x(v' = 3) = 0.2933 D, /x(v' = 4) = 0.2769 D and /x(v' = 5)= 0.2617 D. An RKR analysis allowed the first two moments of the dipole moment function to be derived. Quantum beats were observed for the f-parity A-doublets and the partial resolution of the hyperfine structure allowed the hyperfine energy level ordering to be determined. Accurate molecular constants were also obtained for B(v' = 4 and 5) levels.
