41. Experimental Line Parameters of the Oxygen A-Band Using Frequency-Stabilized Cavity Ring-Down Spectroscopy
Topic: Spectroscopy
Published: 1/1/2008
Authors: D J Robichaud, Joseph Terence Hodges, Linda R. Brown, D Lisak, Piotr Maslowski, Charles E Miller
Abstract: Line intensities, self- and air-broadened linewidths, pressure-induced shifts, and collisional narrowing coefficients were measured from 18 <= J' <= 32 in the P branch of the O2 A-band (12,975 13,055 cm^(-1)). Spectra were recorded using the freque ...

42. Characterization of 3-Color CARS in a 2-Pulse Broadband CARS Spectrum
Topic: Spectroscopy
Published: 11/15/2007
Authors: Young Jong Lee, Marcus T Cicerone, Yuexin Liu
Abstract: We present a new and simple approach to broadband coherent anti-Stokes Raman scattering (CARS) microscopy that yields background-free vibrational spectra. We present evidence for a mechanism where two different frequency components in a continuum pul ...

43. Raman Spectroscopy of n-Type and p-Type GaSb with Multiple Excitation Wavelengths
Topic: Spectroscopy
Published: 10/1/2007
Authors: James E Maslar, Wilbur S. Hurst, C Wang
Abstract: The interpretation of Raman spectra of GaSb can be complicated by the presence of a so-called surface space-charge region (SSCR), resulting in an inhomogeneous near-surface Raman scattering environment. To fully interpret Raman spectra, it is i ...

44. In Situ Characterization of Gas-Phase Species Present During Hafnium Oxide Atomic Layer Deposition
Topic: Spectroscopy
Published: 1/1/2007
Authors: James E Maslar, Wilbur S. Hurst, Donald R Burgess Jr, William Andrew Kimes, Nhan V Nguyen
Abstract: In this work, the species present in the gas phase during atomic layer deposition of hafnium oxide were investigated in an attempt to gain insight into the chemistry of this system. Hafnium oxide was deposited on a silicon substrate using tetrakis(e ...

45. Frequency-stabilized cavity ring-down spectrometer for high-sensitivity measurements of water vapor concentration
Topic: Spectroscopy
Published: 8/12/2006
Authors: Joseph Terence Hodges, D Lisak
Abstract: We present a portable spectrometer that uses the frequency-stabilized cavity ring-down spectroscopy technique to realize high-precision measurements of trace water vapor concentration. Measuring one of the strongest rovibrational transitions in the 1 ...

47. Infrared and Raman Spectroscopy Characterization of Biological Products
Topic: Spectroscopy
Published: 1/1/2005
Author: Vytautas Reipa
Abstract: 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 appli ...

49. Structure of Polystyrene at the Interface With Various Liquids
Topic: Spectroscopy
Published: 9/4/2004
Authors: Clayton S. Yang, P T. Wilson, Lee J Richter
Abstract: 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. ...
