Characterization of the lowest excited-state ro-vibrational level of ${}^{23}$Na${}^{87}$Rb

Junyu He, Junyu Lin, Romain Vexiau +3

Starting from an ultracold sample of ground-state ${}^{23}$Na${}^{87}$Rb molecules, we investigate the lowest ro-vibrational level of the $b^3\Pi$ state with high resolution laser spectr…
