Vibrational Energies of the Hydrogen Bonds of H₃O₂⁻ and H₅O₂⁺
We approximate the vibrational energies of the symmetric and asymmetric stretches of the hydrogen bonds of the molecules H_3O_2^- and H_5O_2^+ by applying an improvement to the standard time-independent Born-Oppenheimer approximation. These two molecules are symmetric around a central hydrogen …

Non-Invasive Intracranial Pressure Method and Monitor
… in all sites. With this being the case, the vibrational energy response of the eye due to an external source can be used to determine a correlation or draw a conclusion concerning the vibrational energy response of the brain would be. And since there is a correlation between the vibrational …

HIGH RESOLUTION LASER SPECTROSCOPIC STUDIES OF THE TRIPLET GROUND STATE, THE 23Πg STATE, AND THE COUPLED A~b STATES OF THE Rb2 DIMER MOLECULE
… separated analysis of the rotational and vibrational Bv and Gv functions to extract the molecular Dunham coefficients from the data. This was to avoid cross correlations between rotational and vibrational parameters because there was limited amount of rotational energy level data which …

A theoretical study of molecular crystals
… embedded many-body expansion of energies, named the binary-interaction method (BIM), has been proposed for molecular clusters and molecular crystals. An infinitely extended, periodic, one-dimensional zigzag hydrogen fluoride chain was studied with this method and the energies, …

Diagrammatic many-body methods for anharmonic molecular vibrational properties
Diagrammatic many-body methods for computing the energies and other properties of anharmonic vibrations have been developed based on the Dyson equation formalism for the single-particle vibrational Green's function and the many-body perturbation theory for the total zero-point energy. Unlike …

Quantum Nuclear Dynamics: Application to Spin-Forbidden Transitions and Lifetime of Vibrational States
… spectroscopic constants and the lifetimes of the vibrational quantum states of these molecules are needed for selecting the suitable molecules for novel ultracold experiments and applications. We investigate the spectroscopic properties and the vibrational state lifetimes of the following …

Magnetic field directed self-assembly of gold Pickering emulsion for preparing patterned film.
… waves. This rise in local charge boosts vibrational energies of molecules in close-surface contact or proximity, resulting in increased IR absorption. The strip-like or any other types of patterns are efficiently achieved through top-down nanofabrication processes like …

Exploring the pressure- and magnetic-field-induced phases of orbital-ordering KCuF3 and single molecule magnet Mn12-acetate: Crystal growth and Raman scattering studies
… plane” direction) does not affect the phonon vibrational energies. However, when the magnetic field is oriented along the easy-axis direction, there is a clear phonon mode splitting at 540 cm-1, indicating a strong spin-phonon coupling associated with this phonon mode in Mn12 acetate. An …

Diffusion of helium isotopes in silicate glasses and minerals : implications for petrogenesis and geochronology
… better described by a distribution of activation energies model . The best estimate for D at 0°C in tholeiitic glass is 5±2 x 10-16 cm2/s, an order of magnitude higher than the results of Kurz and Jenkins (1981) but lower than suggested by Jambon, Weber and Begemann (1985). Measurements in an …
