摘要：

The X (1)Sigma(+) state of NaRb was studied by Fourier-transform spectroscopy. An accurate potential energy curve was derived from more than 8800 transitions in isotopomers (NaRb)-Na-23-Rb-85 and (NaRb)-Na-23-Rb-87. This potential reproduces the experimental observations within their uncertainties of 0.003 cm(-1)-0.007 cm(-1). The outer classical turning point of the last observed energy level (v(')=76, J(')=27) lies at approximate to12.4 Angstrom, leading to an energy of 4.5 cm(-1) below the ground-state asymptote.
