1. The Infrared Spectrum of HOOH+ Trapped in Solid Neon
Topic: Molecular Physics
Published: 10/12/2012
Authors: Warren Elwin Thompson, Catherine L. Lugez, Marilyn E Jacox
Abstract: When a Ne:H2O2 mixture is codeposited at 4.3 K with a beam of neon atoms that have been excited in a microwave discharge, three new, photosensitive absorptions appear which can be assigned to the three infrared-active fundamentals of trans-HOOH+. Wh ...

2. The Infrared Spectrum of NN...CO+ Trapped in Solid Neon
Topic: Molecular Physics
Published: 12/15/2011
Authors: Warren Elwin Thompson, Marilyn E Jacox
Abstract: Codeposition of a Ne:N2:CO = 200:1:1 mixture at 4.3 K with a beam of very pure neon atoms excited to their energy levels between 16.6 and 16.85 eV leads to stabilization in the resulting solid of sufficient NNCO+ for detection of its NN- and CO-stret ...

3. Precision spectroscopy with frequency combs at 3.4 {mu}m
Topic: Molecular Physics
Published: 8/2/2011
Authors: Esther Baumann, Fabrizio Raphael Giorgetta, William C Swann, Alexander M. Zolot, Ian R Coddington, Nathan Reynolds Newbury
Abstract: We discuss precision spectroscopy with a comb-based spectrometer at 3.4 {mu}m. Our goal is to explore comb-based spectroscopy as an alternative method for fast, highly resolved, accurate measurements of gas line shapes. The spectrometer uses dual 1.5 ...

4. GaN Nanowires Grown by Molecular Beam Epitaxy
Topic: Molecular Physics
Published: 8/1/2011
Authors: Kristine A Bertness, Norman A Sanford, Albert Davydov
Abstract: The unique properties of GaN nanowires grown by molecular beam epitaxy are reviewed. These properties include the absence of residual strain, exclusion of most extended defects, long photoluminescence lifetime, low surface recombination velocity,and ...

5. The Infrared Spectra of BF3+ and BF2OH+ Trapped in Solid Neon
Topic: Molecular Physics
Published: 5/20/2011
Authors: Marilyn E Jacox, Warren Elwin Thompson
Abstract: Observations on a Ne:BF3 = 400:1 mixture into which a trace of normal or isotopically enriched water had been introduced, codeposited at 4.3 K with a beam of neon atoms that had been excited in a microwave discharge, demonstrate that a pair of absorp ...

6. Photoexcitation of Free Radicals and Molecular Ions Trapped in Rare-Gas Solids.
Topic: Molecular Physics
Published: 5/2/2011
Author: Marilyn E Jacox
Abstract: The photochemical production of free radicals, molecular ions, and other highly reactive species, their trapping in rare-gas solids for studies of their vibrational and electronic spectra, and the use of secondary photolysis for product identificatio ...

7. Intermolecular potential energy surface and second virial coefficients for the water-CO2 dimer
Topic: Molecular Physics
Published: 4/7/2011
Authors: Allan H Harvey, Richard J. Wheatley
Abstract: The first complete five-dimensional potential energy surface is calculated for the interaction of water and carbon dioxide, using second-order Møller-Plesset perturbation theory (MP2) and coupled-cluster theory with single, double and perturbative tr ...

8. The Infrared Spectra of C2H4+ and C2H3 Trapped in Solid Neon
Topic: Molecular Physics
Published: 2/14/2011
Authors: Marilyn E Jacox, Warren Elwin Thompson
Abstract: When a mixture of ethylene in a large excess of neon is codeposited at 4.3 K with a beam of neon atoms that have been excited in a microwave discharge, two groups of product absorptions appear in the infrared spectrum of the deposit. Similar studies ...

9. Metrology of Molecular Devices made by Flip Chip Lamination
Topic: Molecular Physics
Published: 4/30/2010
Authors: Christina Ann Hacker, Mariona Coll Bau, Curt A Richter
Abstract: Scaling of conventional electronics has continued unabated to dimensions approaching fundamental physical limits. As technology continues to evolve there are increasing demands to identify alternate routes of performing electrical functions. One po ...

10. The A 2E" - X 2A2' Transition of NO^d3^ Trapped in Solid Neon
Topic: Molecular Physics
Published: 4/7/2010
Authors: Marilyn E Jacox, Warren Elwin Thompson
Abstract: NO3 has been stabilized in a neon matrix at 4.3 K in sufficient yield for detection of the absorptions between 7000 and 10000 cm-1 which arise from vibronically allowed transitions from its ground state to levels of the A 2E" state. The results conf ...
