11. Ultrafast Dynamics of Model Molecular Photoswitches in Solid Phase
Published: 12/18/2007
Authors: Tung T. To, Edwin J Heilweil
Abstract: Ultraviolet pump, infrared probe transient absorption studies of the chelatable compound 1, [Mn{?5-C5H4C(O)(SCH3)3}(CO)3], dispersed in room temperature, ~25 m thick polyacryclonitrile (PAN) films are reported for the first time. Irradiation of 1 ...

14. Terahertz Spectroscopy of Dicyanobenzenes: Anomalous Absorption Intensities and Spectral Calculations
Published: 5/24/2007
Authors: Okan Esenturk, Ari Evans, Edwin J Heilweil
Abstract: Terahertz (THz) absorption spectra of the three isomeric structures of dicyanobenzene obtained from chloroform solutions and the solid phase at 298 K are reported. These spectra exhibit enhanced absorption cross-sections over those measured for most ...
