31. Rotational Spectra of the Diastereomers of Soman
Published: 4/1/2004
Authors: R D. Suenram, R S DaBell, Angela R Hight Walker, D J Lavrich, David F Plusquellic, M W Ellzy, J M Lochner, L Cash, J O Jensen, A C Samuels
Abstract: The pure rotational spectrum of the nerve agent Soman has been recorded and assigned using a pulsed molecular beam Fourier transform microwave spectrometer. The spectrum consists of transitions from two different isomers that are likely the [SS] (or ...

32. Continuous-Wave Terahertz Spectroscopy of Plasmas and Biomolecules
Published: 3/1/2004
Authors: David F Plusquellic, T M Korter, Gerald T Fraser, R J Lavrich, Eric C Benck, C R. Bucher, Angela R Hight Walker, J L Domenech
Abstract: Continuous-wave linear-absorption spectroscopy based on THz radiation generated by solid-state photomixers has been applied to the investigation of the dynamics of biomolecules in polyethylene matrices and to line shape studies of HF for diagnostics ...

33. Surface Enhanced Raman Spectroscopy in a Microfluidic Device
Published: 2/1/2004
Authors: D Dunmire, D B Romero, Guangjun Cheng, Angela R Hight Walker
Abstract: Surface enhanced Raman spectroscopy (SERS) is employed to study the solution phase vibrational structure of molecules on gold and silver colloids. Gold and silver colloids show large enhancement factors enabling sub-micromolar detection limits. Using ...

34. Synthesis of Bioconjugated Magnetic Nanoparticles for Magneto-Raman Study
Published: 2/1/2004
Authors: Guangjun Cheng, D B Romero, D Dunmire, Angela R Hight Walker
Abstract: We are investigating the effects of an externally applied magnetic field on the structure and magnetic properties of biomolecules (DNA and proteins). A newly constructed, magneto-Raman confocal microscope system couples a cryo-magnet to a triple grat ...

39. Conformational Analysis of the Jet-Cooled Peptide Mimetic Ethylacetamidoacetate from Torsion-Rotation Spectra
Published: 9/1/2003
Authors: R J Lavrich, Angela R Hight Walker, David F Plusquellic, I Kleiner, R D. Suenram, Jon Torger Hougen, Gerald T Fraser
Abstract: Rotational spectra of two conformers of the dipeptide mimetic, ethyl acetamidoacetate, were measured in a molecular beam using a Fourier-transform microwave spectrometer. In each conformer, internal rotation of the acetyl methyl group gives rise to ...
