1. Analysis of Several High-Resolution Bands of Spiropentane, C5H8
Published: 6/15/2015
Authors: Alfons Weber, A. Maki, J. E Price, Jared Harzan, J. W. Nibler, T. Masiello, T Blake
Abstract: The high resolution absorption spectrum of spiropentane (C5H8) from 200 cm-1 to 4000 cm−1 has been measured and a detailed analysis is presented for eight bands in the region from 700 cm−1 to 2200 cm−1. Two fundamental perpendicula ...

2. High-resolution infrared and electron-diffraction studies of trimethylenecyclopropane ([3]-radialene)
Published: 5/16/2013
Authors: Corey Wright, Joshua Holmes, Joseph W. Nibler, Kenneth Hedberg, James D. White, Lise Hedberg, Alfons Weber, Thomas A. Blake
Abstract: Combined high-resolution spectroscopic, electron-diffraction, and quantum theoretical methods are particularly advantageous for small molecules of high symmetry and can yield accurate structures that reveal subtle effects of electron delocalization o ...

3. High-resolution infrared studies of the V10, V11, V14, and V18 levels of [1.1.1] propellane
Published: 11/15/2012
Authors: Robynne Kirkpatrick, Tony Masiello, Mathew A Martin, Joseph W Nibler, Arthur Maki, Alfons Weber, Thomas A Blake
Abstract: This paper is a continuation of earlier work for which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transi ...

4. Coriolis Analysis of Several High-Resolution Infrared Bands of Bicyclo [1.1.1]pentane-d0 and -d1*
Published: 7/1/2012
Authors: Alfons Weber, A. Perry, M.A. Martin, J. W. Nibler, A. Maki, T. Masiello, T. A. Blake
Abstract: High resolution infrared absorption spectra have been analyzed for two bicycle[1.1.1]pentane isotopologues, C5H8 (-d0) and C5H7D (-d1), where in the latter the D-atom replaces a hydrogen on the C3 symmetry axis such that the molecular symmetry is red ...

5. High-Resolution Infrared Spectra of Spiropentane, C5H8
Published: 9/15/2011
Authors: Alfons Weber, J E Price, K A Coulterpark, Tony Masiello, Joseph W Nibler, A Maki, Thomas A Blake
Abstract: Infrared spectra of spiropentane (C5H8) have been recorded at a resolution (0.002 cm-1) sufficient to resolve for the first time individual rovibrational lines. This initial report presents the ground state constants for this molecule determined fro ...

6. On the determination of C0 (or A0), D0K, H0K, and some dark states for symmetric-top molecules from infrared spectra without the need for localized perturbations
Published: 5/4/2009
Authors: Alfons Weber, Jintao Zhang, Tony Masiello, Thomas A Blake, J Nibler
Abstract: For symmetric top molecules, the normal k = 0, l = 0 and k = 1, l = 1 selection rules for parallel and perpendicular bands, respectively, do not allow the determination of the K-dependent rotational con ...

7. High Resolution Rovibrational Study of the Coriolis-coupled v12 and v15 Modes [1.1.1] Propellane
Published: 1/5/2009
Authors: Alfons Weber, Robynne Kirkpatrick, Tony Masiello, N Jariyasopit, J Nibler, Jintao Zhang, Thomas A Blake
Abstract: Infrared spectra of the small strained cage molecule [1.1.1] propellane have been obtained at high resolution (0.0015 cm-1) and the J, K, and l rovibrational structure has been resolved for the first time. We recently used these spectra to obtain co ...

8. Effect of hydrogen on Pb(Zr,Ti)O^d3^-based ferroelectric capacitors
Published: 1/1/1998
Authors: S Aggarwal, S R Peruse, C W Tipton, H D Drew, T Venkatesan, R Ramesh, D B. Romero, Vyacheslav B Podobedov, Alfons Weber

9. Effect of structural and magnetic transitions in La^d1-x^M^dx^MnO^d3^ (M=Sr,Ca) single-crystals in Raman-scattering
Published: 1/1/1998
Authors: Alfons Weber, D B. Romero, Joseph Paul Rice, H D Drew

10. Evaluation of Raman-scattering in La^d1-x^M^dx^MnO^d3^ single-crystals due to structural and magnetic transitions, ed. by M. Hundley
Published: 1/1/1998
Authors: Vyacheslav B Podobedov, Alfons Weber, D B. Romero, Joseph Paul Rice, H D Drew
Abstract: The study of doped and undoped La1-xMxMnO3 single crystals [x= O to 0.3] in the temperature range from 5 K to 423 K is reported. The activity of phonon vibrational modes in optical spectra is analyzed and a comparison to experimental Raman data i ...
