aCompare the magnitude of intermolecular forces of H2O and O2: [translate] aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, ...
The spectroscopic features of protonated water species in dilute acid solutions have been long sought after for understanding the microscopic behavior of the proton in water with gas-phase water clusters H+(H2O)n extensively studied as bottom-up model sy
One of the most direct probes of the dynamics of this network is the infrared spectrum of the OH stretching vibration3,4,5,6,7,8,9,10,11, which reflects the distribution of hydrogen-bonded structures and the intermolecular forces controlling the structural dynamics of the liquid. Indeed, ...
The temperature at which the liquid's vapor pressure becomes equal to that of Atmospheric pressure is known as the boiling point. The boiling point of any compound is dependent on the pressure of surroundings and the intermolecular forces in t...
The intermolecular distances of the three substances were 0.421, 0.553, and 0.290 nm, respectively. The radial distribution function (RDF) analysis showed that H2O molecules were arranged in the most compact fashion, forming a tight molecular layer. (4) H2O molecules showed a significantly ...
The intermolecular forces of attraction (IMFA) are the interactions occurring between molecules. These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling point ...

An intermolecular coexistent hydrogen bond and a dihydrogen bond of a novel phenol-H2O-diethylmethylsilane (DEMS) complex in the electronically excited states were studied using the time-dependent density functional theory (TDDFT) method. Frontier molecular orbitals analysis revealed that the S2state of...
