All-optical reconstruction of k-dependent transition dipole moment by solid harmonic spectra from ultrashort laser pulses

Optics Express, 2019
Band structure and transition dipole moment play important roles in high-order harmonic generation from solid materials. In this work we provide a new all-optical technique to reconstruct the momentum-dependent transition dipole moment using the harmonic

Increasing the Magnetic Transition Dipole Moment of Chiral Perovskite Through Eu3+ Doping

Advanced Physics Research
Chiral hybrid organic‐inorganic perovskites (HOIPs) are widely investigated due to their superior chiroptical and chiral spintronic properties. Research on the enhancement of chiroptical performance is highly important for the real application of chiral ...

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

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 3-fold symmetry, which prohibits a priori ...

The potential energy function for O2 X(3∑−g ) and the transition dipole moment of the Schumann–Runge band near X-state dissociation [PDF]

, 1989
Emission spectra were analyzed for transitions of O2 (B 3∑−u, v’→X 3∑−g, v‘) with v‘ as high as 35. The X 3∑−g potential energy function, Vx (r), was determined nearly to the dissociation limit with an estimated accuracy of ±50 cm−1.

Transition dipole moment orientation in films of solution processed fluorescent oligomers: investigating the influence of molecular anisotropy

, 2016
The low light-outcoupling efficiency of organic light emitting diodes (OLEDs) is limiting their performance. Orientation of the transition dipole moment of the emitting molecules in the plane of the diodes can improve the luminance of OLEDs.

The dipole moment function and vibrational transition intensities of OH [PDF]

The Journal of Chemical Physics, 1989
The relative intensities of nine pairs of rovibrational transitions of OH in the v=1←0 fundamental have been measured by flash kinetic infrared absorption spectroscopy. Each pair of transitions originates from a common rotational and spin–orbit state, so that relative intensities are independent of the OH number density and quantum state distribution ...
