Structure and weak hydrogen bonds in liquid acetaldehyde
(2004-08-30)
Monte Carlo simulations have been performed to investigate the structure and hydrogen bonds formation in liquid acetaldehyde. An all atom model for the acetaldehyde have been optimized in the present work. Theoretical ...
Quantum confinement in hydrogen bond
(Wiley-Blackwell, 2015-06-15)
In this work, the quantum confinement effect is proposed as the cause of the displacement of the vibrational spectrum of molecular groups that involve hydrogen bonds. In this approach, the hydrogen bond imposes a space ...
The effect of confinement on the electronic energy and polarizability of a hydrogen molecular ion
(Wiley-Blackwell, 2016-04-05)
The electronic energy and the polarizability of a confined hydrogen molecular ion in the ground state and the first excited state, for cavities of different volumes, are calculated using the variational method. In the ...

Hydrogen Bonds: Stickiness of the Hydrogen Bond (Ann. Phys. 9/2018)
(Wiley VCH Verlag, 2018-09)
The dielectric response of bulk water follows laws of continuum electrostatics,a scheme often extrapolated without justification to treat confined interfacialwater, where the Debye polarization ansatz breaks down and ...
CLOPPA analysis of the molecular polarizability and the energy of strong intramolecular hydrogen bonds: Resonance assisted?
(American Chemical Society, 2012-11)
The contributions from localized orbitals within the polarization propagator approach (CLOPPA) method is applied to investigate the influence of the π system on the polarizability of the intramolecular hydrogen bond of ...
Supercritical hydrogenation processes experimental results on the fluid phase behavior of binary and ternary mixtures of hydrogen, propane and tripalmitin
(Elsevier Science, 2003-03-17)
The problems of low reaction rate and cis-trans isomerization encountered in the gas-liquid catalyzed hydrogenation of vegetable oils can be overcome by using a supercritical fluid to bring the reactive mixture into a ...
Molecular orbital calculations of hydrogen bonding in ammonia - Formic acid system in the presence of electric fields
(2004)
The effects of electric fields on hydrogen bonding in ammonia-formic acid system, are examined with STO-3G and 6-31 G(d) wavefunctions. This system was used in a previous work to model hydrogen bonding in crystalline amino ...
