Vibrations, Tunneling, and Transition Dipole Moments in the Water Dimer [PDF]

The Journal of Physical Chemistry A, 2001
The wave functions of the dimers (H2O)2 and (D2O)2 computed earlier [Groenenboom et al. J. Chem. Phys. 2000, 113, 6702] are analyzed. Their tunneling and vibrational behavior is inspected and compared with earlier experimental assignments of the tunneling and vibrational modes.

General calculation of $4f-5d$ transition rates for rare-earth ions using many-body perturbation theory

, 2005
The $4f-5d$ transition rates for rare-earth ions in crystals can be calculated with an effective transition operator acting between model $4f^N$ and $4f^{N-1}5d$ states calculated with effective Hamiltonian, such as semi-empirical crystal Hamiltonian ...

A Method for Measuring the $6S_{1/2} \leftrightarrow 5D_{3/2}$ Magnetic Dipole Transition Moment in {Ba}$^{+}$

, 2013
We propose a method for measuring the magnetic dipole (M1) transition moment of the $6S_{1/2} \big(\mathrm{m}=-1/2\big)\leftrightarrow 5D_{3/2}\big(\mathrm{m}=-1/2\big)$ transition in single trapped Ba$^{+}$ by exploiting different symmetries in the ...

B-field Determination from Magnetoacoustic Oscillations in kHz QPO Neutron Star Binaries: Theory and Observations [PDF]

, 2001
We present a method for determining the B-field around neutron stars based on observed kHz and viscous QPO frequencies used in combination with the best-fit optical depth and temperature of a Comptonization model. In the framework of the transition layer

Muon (g − 2) in the B-LSSM

Journal of High Energy Physics, 2021
The difference between the updated experimental result on the muon anomalous magnetic dipole moment and the corresponding theoretical prediction of the standard model on that is about 4.2 standard deviations. In this work, we calculate the muon anomalous

Transition Dipole Moments and Transition Probabilities of the CN Radical

The Astrophysical Journal Supplement Series, 2018
Abstract This paper studies the transition probabilities of electric dipole transitions between 10 low-lying states of the CN radical. These states are X2Σ+, A2Π, B2Σ+, a4Σ+, b4Π, 14Σ−, 24Π, 14Δ, 16Σ+, and 16Π. The potential energy curves are calculated using the CASSCF method, which is followed by the icMRCI approach with the Davidson ...

Spontaneous Fluctuations of Transition Dipole Moment Orientation in OLED Triplet Emitters [PDF]

The Journal of Physical Chemistry Letters, 2015
The efficiency of an organic light-emitting diode (OLED) depends on the microscopic orientation of transition dipole moments of the molecular emitters. The most effective materials used for light generation have threefold symmetry, which prohibit a priori determination of dipole orientation due to the degeneracy of the fundamental transition.

Measurement of Linear Stark Interference in 199Hg

, 2011
We present measurements of Stark interference in the 6$^1S_0$ $\rightarrow$ 6$^3P_1$ transition in $^{199}$Hg, a process whereby a static electric field $E$ mixes magnetic dipole and electric quadrupole couplings into an electric dipole transition ...

Understanding the Effect of Resistance Temperature Detector Temperature Controllers on Microstructural Alignment in Magnetic Freeze Casting

Advanced Engineering Materials, EarlyView.
The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

Electric transition dipole moment in pre-Born–Oppenheimer molecular structure theory [PDF]

The Journal of Chemical Physics, 2014
This paper presents the calculation of the electric transition dipole moment in a pre-Born–Oppenheimer framework. Electrons and nuclei are treated equally in terms of the parametrization of the non-relativistic total wave function, which is written as a linear combination of basis functions constructed from explicitly correlated Gaussian functions and ...
