Starting from an ultracold sample of ground-state NaRb molecules, we investigate the lowest ro-vibrational level of the bΠ state with high resolution laser spectroscopy. This electronic spinforbidden XΣ ↔ bΠ transition features a nearly diagonal Franck-Condon factor and has been proposed useful for probing and manipulating the ultracold molecular gas. We measure the transition strength directly by probing the ac Stark shift induced by near resonance light and determine the total excited-state… Expand
