Tunneling Splitting in Polyatomic Systems

چکیده
Tunneling phenomenon is well recognized as one of the most important quantum mechanical effects from the dawn of quantum mechanics, and it actually plays crucial role in all branches of science from elementary particle physics to biology. In this work, we consider one of the basic phenomena: tunneling splitting in multi-dimensional double well potential and present a canonically invariant instanton theory applicable to vibrationally excited states of polyatomic molecules. For the ground state tunneling splitting such a theory has been developed recently in [1]. It gives

Perturbation theory approach to dynamical tunneling splitting of local mode vibrational states in ABA molecules
We introduce a point of view for treating the dynamical tunneling splitting of symmetric local mode vibrational states in ABA molecules (A = H typically) which is the one we have employed in treating the vibrational spectroscopy of CH overtones in molecules such as (CXs),YCCH. Namely, the vibrational coupling corresponding to the dynamical tunneling in semiclassical mechanics via many intermedi...
متن کاملSelective Bond Breaking of Single Iodobenzene Molecules with a Scanning Tunneling Microscope Tip
Controlled step-by-step dissociation of single iodobenzene molecules has been performed at Cu(111) step-edges using tunneling electrons from a scanning tunneling microscope (STM) tip at 12 K. We show that the threshold tunneling electron energies to break a single bond inside a polyatomic molecule can be determined by using I-V spectroscopy of single molecules. Electron energies of 1.5±0.1 eV a...
متن کاملConstructing a Body-Fixed Reference Frame for a Polyatomic Molecule
An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
متن کاملThe Level Splitting Distribution in Chaos-assisted Tunneling
A compound tunneling mechanism from one integrable region to another mediated by a delocalized state in an intermediate chaotic region of phase space was recently introduced to explain peculiar features of tunneling in certain two-dimensional systems. This mechanism is known as chaos-assisted tunneling. We study its consequences for the distribution of the level splittings and obtain a general ...
متن کاملI-E-1 Nonadiabatic Transition and Chemical Dynamics: Multi-Dimensional Tunneling Theory and Applications of the Zhu-Nakamura Theory
Tunneling and nonadiabatic transition are the most important quantum mechanical effects in chemical dynamics. They are important not only for understanding the dynamics properly, but also for controlling molecular functions. The Zhu-Nakamura (ZN) theory can be combined with the quasi-classical trajectory method and with the IVR (Initial Value Representation)-type semiclassical theory to deal wi...
