摘要：

A series of rotational wave packet recurrences originating from single 2-level coherent rotational superpositions are observed in the E((1) Sigma(g)(+)) state of Li-2. The rotational wave packet is created by ultrafast laser excitation from a specific re-vibrational level in the A((1) Sigma(u)(+)) state selected by cw laser excitation. Using this technique the rotational constant and the centrifugal distortion constant are determined for high J levels of the upsilon=9 vibrational level in the E((1) Sigma(g)(+)) state. This technique is discussed vis-a-vis traditional forms of ultrafast rotational coherence spectroscopy where information primarily at low J is obtained.
