摘要	The quantum coherent motion of excitons on a dimerized chain with alternating site energies and intersite interactions is studied analytically. Exact solutions for the propagators at any site, the mean polarization and mean-square displacement are obtained. Through these exact results and accompanying numerical analysis, it is shown that the increase of the site-energy mismatch and the hopping disturbance will tend to strengthen the localization.
