21. Electron-Impact Total Ionization Cross Sections of Hydrocarbon Ions
Series: Journal of Research (NIST JRES)
Published: 2/1/2002
Authors: Karl K Irikura, Yong Sik Kim, M A Ali
Abstract: The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections has been applied to CH^d2^^u+^, CH^d3^^u+^, CH^d4^^u+^, C^d2^H^d2^^u+^, C^d2^H^d4^^u+^, C^d2^H^d6^^u+^, and H^d3^O^u+^. The cross sections for the hydrocarbo ...

22. Erratum: 'Thermochemistry of Disulfur Decafluoride, S^d2^F^d10^' [J. Chem. Phys. 103, 10162 (1995)]
Published: 9/1/2001
Author: Karl K Irikura
Abstract: Contrary to the footnotes to Tables II and III found in Ref. 1, HF/6-31G* vibrational frequencies were scaled by 0.893. The correct values were shown in the original tables. However, the frequency of the {nu}^d15^ vibration was inadvertently scaled ...

23. The Reaction of BF^d3^ with H^d2^O Infrared Spectrum of BF^d2^OH Trapped in Solid Neon
Published: 10/1/2000
Authors: Marilyn E Jacox, Karl K Irikura, Warren Elwin Thompson
Abstract: When a Ne:BF^d3^ sample is passed through a long stainless steel deposition line before being frozen onto a cryogenic observation surface maintained at approximately 5 K, the infrared spectrum of the resulting deposit includes prominent absorptions a ...

25. Electron-Impact Ionization Cross Section Database (Version 2.0)
Published: 9/1/2000
Authors: Yong Sik Kim, Karl K Irikura, M E Rudd, D Zucker, M A. Zucker, J S Coursey, Karen J Olsen, G G Wiersma
Abstract: This is a database primarily of total ionization cross sections of molecules by electron impact. The database also includes cross sections for a small number of atoms and energy distributions of ejected electrons for H, He, and H^d2^. The cross secti ...

26. Electron-Impact Total Ionization Cross Sections of SF^dx^ (x = 1-5)
Published: 7/1/2000
Authors: M A Ali, Karl K Irikura, Yong Sik Kim
Abstract: Total cross sections for electron impact ionization are necessary quantities for numerical modeling of plasma chemistry and for quantitative mass-spectrometric gas analysis. Theoretical cross sections for SF, SF^d2^, SF^d3^, SF^d4^, and SF^d5^ are c ...

27. Electronic Structure of BC1 Determined by ab Initio Calculations and Resonance-Enhanced Multiphoton Ionization Spectroscopy
Published: 3/14/2000
Authors: Karl K Irikura, Russell D Johnson III, Jeffrey W Hudgens
Abstract: The mass-resolved, one-color, 2 + 1 resonance-enhanced multiphoton ionization spectrum of transient boron monochloride (BC1) between 348 nm and 369 nm is reported. Vibrational and rotational bands of the ^10^B^35^C1, ^11^B^35^C1, ^10^B^37^C1, and ^ ...

28. Electron-Impact Ionization Cross Sections for Polyatomic Molecules, Radicals, and Ions
Published: 3/1/2000
Authors: Yong Sik Kim, Karl K Irikura
Abstract: The binary-encounter-Bethe (BEB) model for calculating electron-impact ionization cross sections for molecules is described with emphasis on polyatomic molecules and their radicals and ions. The BEB model provides an analytic formula for the cross s ...

29. Electron-Impact Total Ionization Cross Sections of Molecular Ions
Series: Journal of Research (NIST JRES)
Published: 3/1/2000
Authors: Yong Sik Kim, Karl K Irikura, M A Ali
Abstract: The Binary-Encounter-Bethe (BEB) model for electron-impact total ionization cross sections of neutral molecules has been modified for molecular ions. The total ionization cross section for H^u+^^d2^, N^u+^^d2^, CD^u+^, and CO+ from the modified BEB ...
