HF inversion in the 2,5-dihydrofuran⋯HF complex

The Journal of Chemical Physics, 2001
The rotational spectrum of the hydrogen bond heterodimer 2,5-dihydrofuran⋯HF has been investigated in the frequency region 6–18.5 GHz using molecular beam Fourier transform microwave spectroscopy. The R-branch μa-type spectra of the parent, 2,5-dihydrofuran⋯DF, Cα13-2,5-dihydrofuran⋯HF and Cβ13-2,5-dihydrofuran⋯HF species have been measured.

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 ...

The Established Therapies: HF-PEF and HF-REF

2016
Over the last few decades, our understanding of the pathophysiology, and subsequently treatment, of chronic heart failure with reduced ejection fraction (HFrEF) has grown considerably. While diuretics and digoxin were once the pillars of treatment for HFrEF, they did not offer any mortality benefits.

Second virial coefficient of gaseous HF and rotational inelastic scattering for HF-HF collisions

Molecular Physics, 1984
A recently determined intermolecular potential for HF has been used to calculate the second virial coefficient of the gas in the temperature range 275-9000 K and the rotational inelastic cross sections for HF-HF collisions at a collision energy of 300 cm-1.

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.
