This technique is being used to measure vibrational spectra of molecules undergoing photochemistry. If the pulse is short compared to a vibrational period, it is possible to excite a nonstationary state which can be described by wavepacket motion on the excited and ground states of the molecule. Before respondent answered the amended petition, Charles filed a motion to stay. The New Laws (Spanish: Leyes Nuevas), also known as the New Laws of the Indies for the Good Treatment and Preservation of the Indians were issued on November 20, 1542, by Charles V, Holy Roman Emperor (King Charles I of Spain) and regard the Spanish colonization of the Americas. With a sufficiently short optical pulse, it is possible to excite the entire manifold on Franck-Condon connected states for the first excited singlet for a molecule in solution. Pro se petitioner Dontae Charles filed an amended petition for writ of habeas corpus under 28 U.S.C. Shank's group hopes to use these investigations to determine the role of solvent interactions and internal molecular degrees of freedom in the dephasing process. Two and three pulse photon echo experiments have been performed using 6 femtosecond optical pulses. In the past, attempts at such measurements have been frustrated by the lack of adequate time resolution. Recent work in his laboratory has included the study of dephasing of an optically excited polarization of a molecule in solution. In his laboratory his group is currently performing measurements which permit them to probe molecular dynamics in solution in a time short compared to a molecular vibration. Such techniques have shown great promise for exploring a new class of problems concerning nonequilibrium phenomena in the condensed phase. Recent advances in laser pulse generation and measurement techniques have opened up the possibility of experimental investigations in the femtosecond time domain. Professor Shank is intrigued by ultrafast processes in matter that occur on a time scale measured in femtoseconds. Physical Chemistry - Ultrafast dynamics of molecular vibrations and chemical reactions are studied with femtosecond optical pulses. Professor Emeritus of Chemistry, Physics, Electrical Engineering and Computer Sciences
