Аннотация:Laser induced fluorescence spectra of the C (1)Sigma(+)-X (1)Sigma(+) system of (NaRb)-Na-23-Rb-85 and (NaRb)-Na-23-Rb-87 have allowed vibrational levels of the electronic ground state up to v(’)=76, spanning 99.85% of the potential well to be observed. The ground-state term values have been fitted to a Dunham polynomial expansion, and also to a direct modified Lennard-Jones (MLJ) potential. The analytical MLJ construction allowed us to match previous measured term values for v(’)less than or equal to30 with long-range behavior of the potential through the intermediate internuclear distance region covered by the present investigation.
