Researchers of the Dalian Institute of Chemical Physics,Chinese Academy of Sciences,China,have developed time-dependent wavepacket method,which has been widely used to investigate molecular dynamics in strong laser field physics since 1997 (published in 1997 Chem.Phys.Lett.271 204).Previously,this method has been developed to track electronic and nuclear wavepacket motions (published in 2005 Phys.Rev.Lett.95 123001,2006 Phys.Rev.A 74 063417).
