U. Even et al., TIME EVOLUTION OF VERY HIGH RYDBERG STATES OF LARGE AROMATIC-MOLECULES - A KINETIC-ANALYSIS, Chemical physics letters, 210(4-6), 1993, pp. 416-422
A long (miroseconds) and shorter (approximately 1 mus) decay channel a
re resolved in the time evolution of very high Rydberg states of large
aromatic molecules. A simple kinetic analysis is presented and applie
d to the very detailed results available for tetracene. It is conclude
d that under our experimental conditions the time evolution is due to
intramolecular processes. The various possible decay channels are disc
ussed.
