HF–HF differential scattering cross sections

The Journal of Chemical Physics, 1990
Close-coupled scattering calculations have been carried out for collisions between HF molecules in their ground vibrational state at a total energy of 1480 cm−1. State-to-state integral and differential cross sections were determined for transitions j1j2→j′1j′2, which refer to collisions HF(j1)+HF(j2)+ΔE→HF(j′1) +HF(j′2), where ΔE is the energy gap ...

HFS

Proceedings of the fourth workshop on I/O in parallel and distributed systems part of the federated computing research conference - IOPADS '96, 1996
The Hurricane File System (HFS) is designed for (potentially large-scale) shared-memory multiprocessors. Its architecture is based on the principle that, in order to maximize performance for applications with diverse requirements, a file system must support a wide variety of file structures, file system policies, and I/O interfaces.

Electric dipole moments of HF–C2H2, HF–C2H4, and HF–C3H6

The Journal of Chemical Physics, 1985
Electric dipole moments of HF–cyclopropane, HF–ethylene, and HF–acetylene have been determined using the molecular beam electric resonance technique. The dipole moments of HF–C3H6, HF–C2H4, and HF–C2H2 are 2.5084(28), 2.3839(45), and 2.3681(28) D, respectively.

Theoretical Potential Energy Curves for OH, HF+, HF, HF−, NeH+, and NeH

The Journal of Chemical Physics, 1972
Ab initio calculations have been carried out on the ground states of OH, HF+, HF, HF−, NeH+, and NeH. Extended basis sets were used and electron correlation was included by way of first-order wavefunctions. Dissociation energies and other spectroscopic constants are in good agreement with available experimental data except for the bond distance of HF+.

Models for hydrogen-bonded π systems: ethylene⋯HF, allene⋯HF and cumulene⋯HF

Journal of Molecular Structure, 1988
Abstract Minima in the electrostatic energy, for accessible orientations, have been located for complexes of hydrogen fluoride with ethylene, allene and cumulene using a version of the Buckingham-Fowler model. The predicted equilibrium structures agree with available experimental results and with Legon and Millen's rules.

Formation of Powdered Hf–Ni, Hf–Cu and Hf–Ru Materials by Mechanical Alloying Methods

Materials Science and Engineering, 1988
Abstract Alloys of HfNi and HfCu were synthesized by mechanical alloying methods. In each system, single-phase amorphicity was found over a wide range of compositions using X-ray diffraction and differential thermal analysis. In a contrasting investigation of Hf50Ru50, the equilibrium compound was formed.
