Computational Study of Intramolecular O-h Stretching Vibrations in the Two Rotamers of Free Formic Acid
O-H stretching vibrations of the two formic acid rotamers were studied using a static approach, based on calculation of the corresponding 1D vibrational potential and subsequent solution of the vibrational Schrödinger equation, and with a dynamic approach, based on Born-Oppenheimer molecular dynamics simulations, followed by computation of partial autocorrelation functions and their subsequent ...
متن کاملAlgebraic Description of Anharmonic Stretching Vibrations.
A U(2) algebraic model is presented to describe stretching vibrations of XYn (n = 2, 3, and 4) systems, where anharmonic interactions between the bond modes are considered. This model in a limit corresponds to an anharmonically coupled local-mode model. As an example, the model for a molecule XY4 is applied to recently observed spectra of methane in both gas and liquid phases, and the results o...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
15 صفحه اولThe vibrational group frequency of the N-O* stretching band of nitroxide stable free radicals.
The group frequency of the N-O radical stretching vibration has received scant attention in the literature. The few existing treatments of the vibrational spectroscopy of nitroxides are incomplete at best and potentially misleading to workers in the field. To close this gap in the available knowledge, the existing literature on the vibrational spectra of nitroxide stable free radicals is critic...
متن کاملThe Subadditive Ergodic Theorem and Generic Stretching Factors for Free Group Automorphisms
Given a free group Fk of rank k ≥ 2 with a fixed set of free generators we associate to any homomorphism φ from Fk to a group G with a left-invariant semi-norm a generic stretching factor, λ(φ), which is a noncommutative generalization of the translation number. We concentrate on the situation when φ : Fk → Aut(X) corresponds to a free action of Fk on a simplicial tree X, in particular, when φ ...
