Infrared and Raman Spectroscopy Characterization of Biological Products

January 1, 2005
Author(s)
Vytautas Reipa
Both infrared and Raman are increasingly applied in biomolecular structure characterization, thus getting acceptance alongside traditional bioanalytical techniques. Physical principles and biological sampling requirements are reviewed. Advanced

Samples and Standards

December 13, 2004
Author(s)
Richard M. Lindstrom, C Yonezawa
For analytical accuracy, the detailed interaction of neutrons with the sample is of more importance in prompt-gamma activation analysis (PGAA) with a neutron beam than in conventional activation analysis. Selection of an optimum sample size and shape is

Fermi Level Alignment and Electronic Levels in Molecular Wire Self-Assembled Monolayers on Au

October 1, 2004
Author(s)
Christopher D. Zangmeister, Steven W. Robey, Roger D. van Zee, Yuxing Yao, J M. Tour
A combination of one- and two-photon photoelectron spectroscopies are used to determine the electronic structure around the Fermi level for self-assembled monolayers of a prototypical molecular wire , 4,4 -(ethynylphenyl)-1-benzenethiol (C6H5-C≡C-C6H4-C≡C-

Structure of Polystyrene at the Interface With Various Liquids

September 4, 2004
Author(s)
Clayton S. Yang, P T. Wilson, Lee J. Richter
Vibrationally resonant sum frequency generation (VR-SFG) is used to determine the structure of the phenyl side groups of deuterated polystyrene at the liquid/solid interface for the nonsolvent liquids: hexane, methanol, ethanol, glycerol, and water. The
