Abstract

Through a mixed level, which has characters of both the A ¹Σ _u ⁺ and b ³Π _u states of Li ₂, several singlet and triplet Rydberg states are accessed simultaneously using an ultrafast laser. The electronic, vibrational and rotational wave packets of these Rydberg states are detected. Since a single member of the excited superposition, 2 ³Σ _g ⁺ (v = 12, N = 16), is predissociative, the intensities of the quantum beats that have a component of this state decrease much faster with time (≈250 ps) than the other stable states. The polarization dependence of the quantum beats is utilized to assign the spectra.
