Interstellar Isomers: The Importance of Bonding Energy Differences

October 10, 2005
Author(s)
A J. Remijan, J M. Hollis, Francis J. Lovas, David F. Plusquellic, P R. Jewell
We present new observations of large cyanide molecules and their corresponding isocyanide isomers toward the Sgr B2(N)molecular cloud. We report the first detection of the JK=10-00 transition of methyl isocyanide (CH3NC) with the 100-m Green Bank Telescope

Submillimeter and THz Detection of Chemical-Warfare Agents in Air

December 31, 2004
Author(s)
Vyacheslav B. Podobedov, R J. Lavrich, T M. Korter, Gerald T. Fraser, David F. Plusquellic, A C. Samuels
Experimental measurements and theoretical calculations were performed to assess the potential for using continuous-wave submillimeter and THz (far-infrared) linear-absorption spectroscopies to detect chemical-warfare agents in air at ambient temperatures

Rotational Spectra of the Diastereomers of Soman

April 1, 2004
Author(s)
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
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 [RR])

Continuous-Wave Terahertz Spectroscopy of Plasmas and Biomolecules

March 1, 2004
Author(s)
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
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 of

Rotational Spectra, Conformational Structures and Dipole Moments of 2-(Ethylthio) Ethanol by Jet-Cooled FTMW and Ab Initio Calculations

January 1, 2004
Author(s)
R D. Suenram, David F. Plusquellic, Francis J. Lovas, A H. Walker, Q Liu, L H. Xu, J O. Jensen, A C. Samuels
The rotational spectra of three low-energy conformers of 2-(ethylthio)ethanol also known as ethyl 2-hydroxyethylsulfide or hydroxyethylethyl sulfide (HOEES), together with the monosubstituted C and 34S isotopic forms of the two lowest energy conformers

Rotational Spectrum of Soman
