Kokkin DL, Schmidt TW.
PMID: 16671689
J Phys Chem A. 2006 May 11;110(18):6173-7. doi: 10.1021/jp057441v.

The electronic excited-state properties of a series of dehydrogenated polycyclic aromatic hydrocarbons from phenyl through to decacyl are reported. The radicals were investigated by use of time-dependent density functional theory in conjunction with the B3LYP functional. The pi and...

The Review of scientific instruments

Swift DC.
PMID: 18248049
Rev Sci Instrum. 2008 Jan;79(1):013906. doi: 10.1063/1.2833824.

X-ray diffraction was demonstrated from shock-compressed polycrystalline metals on nanosecond time scales. Laser ablation was used to induce shock waves in polycrystalline foils of Be, 25-125 microm thick. A second laser pulse was used to generate a plasma x-ray...
