✦ Synopsis

The laser-induced fluorescence or Rb, molecules has been obsewed in the 9000-I 2500 cm-' spcclral range after enci[aGon by a s~yryl 9 ring dye laser. The A'B; -+ X "; fluorescence speclra were recorded by Fourier transrorm specwoscopy. Accurale molecular consktnw were derived Ior the ground electronic slate up IO the vibrslional level v -72 and Tar ro!aGonal quantum numbers J ranging rrom .32 LO 206. The IPA polenlial curve was consrrucled from these dala. The main molecular consLants [or the "Rb, X 'xl slale are: U. = 57.781 cm-'. w,x, -0.13911 cm-'. 8, = 22.403 x lo-" cm-'. 0. =1.35X IO-' cm-'. and R, = 4.2099 A.
