By monitoring single vibronic level pump-probe fluorescence depletion, the rotationally resolved spectra of the 46 482 cm(-1) band of CS2 were recorded. The molecular constants are v(0) = 46 481.51(11) cm(-1), B = 0.098 09(24) cm(-1), and D = 6.7(9.3) x 10(-8) cm(-1). The J-dependent predissociation rate was analyzed. At low J levels the predissociation rate is dominated by the energy separation and the coupling between the bound and the repulsive states, while at high J levels the rate is controlled by the tunneling through the barrier of the centrifugal potential.
