The concept of hybrid water molecules is defined and a theoretical model describing the behavior of such molecules when sampling a water vapor is constructed. The model describes translational motion of water molecules near the gas-condensed matter interface taking into account the effect of force ...
In this ‘nanoconfinement’, the hydration structures—how water molecules or their constituent elements arrange themselves—determine the ability of the original material to store ions (positively or negatively charged atoms or groups of atoms). This storage of water or charge means that such layered...
The application of optical forces has allowed unprecedented control over the motion of atoms leading to laser cooling and trapping and Bose-Einstein condensation. More recently, the manipulation of cold neutral polar molecules using electrostatic fields has been used to create slow cold molecules in th...
A method for studying the time dependence of the short-range molecular order of water has been proposed. In the present study, water is considered as a dynamic network between molecules at distances not exceeding 3.2 Å. The instantaneous configurat
By using the oscillatory motion of nitric oxide molecules in these potentials, we have demonstrated rapid deceleration or acceleration in a molecular beam to well-defined velocities on a length scale of less than 535 nm. We reduce the kinetic energy of the molecules in a cold molecular beam by...
In the video, striking a water bottle provides a site for ice crystals to form, or in other words, a site for nucleation. Nucleation is a process where the molecules in a liquid start to gather into tiny clusters, arranging in a way that will define the crystal structure of the solid....
For a spherical molecule with rapid internal motions, the spectral density functions are (Lipari and Szabo, 1982):(4){formula not available as MathML}where τ0 is the rotational correlation time of the molecules, τe is the effective correlation time for fast internal motion, and S2 is the...
that is to say, they are like loaded springs just waiting to go off. Other molecules (often oxygen) hold the ‘key’ to unlocking the spring, and when the springs go off, as you can imagine, it is like a room full of mousetraps and ping-pong balls – and all that motion – means...
Thus, it was proposed that the migration ability of FRs in water is distinctly higher than that in ice, likely because the migration performance of FRs is closely related to the intermolecular distance of water molecules. Furthermore, the RE of Cr(VI) in ice decreased gradually with the ...
The site-specific IR spectral signatures reveal two distinct structures for the internal and surface four-coordinated water molecules, which are ice-like and liquid-like, respectively. The effect of inter-molecular interaction between water molecules is addressed, and the vibrational resonance is found...
