The use of infrared kinetic spectroscopy to study small free radicals
(1998)
The technique of infrared kinetic spectroscopy has been used to study the reaction of the propargyl radical (C3H3) with nitric oxide (NO). The overall rate constant at the high pressure limit for the reaction was determined ...
Synthesis, characterization and magnetic property studies of copper-based phosphate and silicate compounds containing nanosize transition metal oxide frameworks
(1996)
The search for novel compounds with nanosize transition metal oxide frameworks is important for the study and understanding of materials with interesting and important magnetic and electronic properties. These low-dimensional ...
Conjugate gradient density matrix search: A linear scaling alternative to diagonalization
(1997)
Advances in the computation of the Coulomb, exchange, and correlation contributions to Gaussian-based Hartree-Fock and density functional theory Hamiltonians have demonstrated near-linear scaling with molecular size for ...
Magnetic and chemical effects in x-ray resonant exchange scattering in rare earths and transition metal compounds
(1994)
The increased availability of synchrotron x-ray sources has facilitated the development of new diffraction techniques based on x-ray resonant exchange scattering (XRES). Resonant electric dipole (E1) and quadrupole (E2) ...
Band evolution and shell structure in large clusters: Aluminum(3-60)anion, copper(1-1113)anion, silver(1-58)anion, and gold(1-223)anion
(1990)
Photoelectron spectroscopy of negatively, charged clusters of aluminum, copper, silver, and gold reveals electronic shell structure and electron energy band development. Photodetachment experiments on Au$\sb6\sp-$ also ...
Hydrogen chemisorption on transition metal clusters
(1991)
Positively charged clusters of V, Nb, Ta, Co, Rh, Ir, and Ni in the size range of 3-26 atoms were generated by laser vaporization in a supersonic nozzle and injected into the ion trap of a Fourier transform ion cyclotron ...
Allostery and assembly oflac repressor protein
(1998)
Allostery in lac repressor ligand binding is based upon the ability of the protein to assume alternate ligand-bound conformations. The X-ray crystal structures of repressor bound to different ligands indicate the end points ...
Synthesis and in vitro characterization of a bone-vectored carbon(60) derivative
(1999)
The first tissue-vectored fullerene derivative, C60 (OH)16AMBP (4,4-bisphosphono-2-(polyhydroxyl-1,2-dihydro-1,2-methanofullerene[60]-61-carboxamido)-butyric acid), designed to target bone tissue, has been synthesized, ...
Studies of oriented molecules using coincidence time-of-flight mass spectroscopy
(1999)
A beam of symmetric top (CX3Y) molecules is state-selected using an inhomogeneous hexapole electric field and then oriented by homogeneous electric fields. A fast neutral atomic potassium beam produced via charge-exchange ...
Molecular beam studies of excitation and electron transfer reactions
(1997)
Two studies were performed using crossed molecular beams. The first system studied was the reaction $\rm Na\sp* + KBr \to NaBr + K\sp*,$ determining how fine structure is transmitted through a reactive collision. Each fine ...
