 Title: DETERMINATION OF THE LONG RANGE POTENTIAL AND DISSOCIATION ENERGY OF THE $Na_{2} 1^{3}\Delta_{g}$ STATE. $B\Pi$. Creators: Tsai, C. C.; Li, Li; Whang, Thou-Jen; Wang, H.; Lyyra, A. M.; Bahns, J. T.; Stwalley, W. C. Issue Date: 1994 Publisher: Ohio State University Abstract: Extensive studies on the $NA_{2}\ 1^{3} \Delta_{g}$ state from $v = 0$ up to $v = 94$ by perturbation Facilitated Optical-Optical Double Resonance spectroscopy with an Ultrasensitive Ion $Detector^{1}$ has allowed the accurate determination of the long range potential and the dissociation energy. This gives an improved value of Do as $7096.56 \pm 0.03 cm^{-1}$. Such high resolution spectroscopy also reveals the hyperfine structures at various rotational quantum numbers ranging from $N = 2$ to $N = 51$. Description: $^{1}$. C.-C. Tsai, J. T Bahns, and W. C.
