Orientation of molecules with a small dipole moment using cyclic wave packets
نویسندگان
چکیده
A robust and versatile method is demonstrated to maintain, for an arbitrary time, quasiconstant and strong orientation for molecules with minute dipole moments. The procedure is based on submitting molecules in cyclic wave packets to periodic trains of nonresonant pulses in an electrostatic field. We show that approximate cyclic states can be created by suddenly switching off a long laser pulse. A control scheme to remove the static field without spoiling orientation is suggested, which would permit large field-free orientation between pulses.

Correlating the transition dipole moment orientation of phosphorescent emitter molecules in OLEDs with basic material properties
The orientation of the emissive dipole moment of seven iridium-based phosphorescent emitter molecules commonly used in organic light-emitting diodes (OLEDs) is investigated. The orientation of Ir(ppy)3, Ir(ppy)2(acac), Ir(chpy)3, Ir(dhfpy)2(acac), Ir(BT)2(acac), Ir(MDQ)2(acac), and Ir(piq)3 is determined by measuring the angle dependent spectral radiant intensity of the transverse magnetic pola...
متن کاملThe infrared spectrum of cyclic-N3: theoretical prediction.
We have carried out the first calculations of the infrared absorption spectrum of cyclic-N(3). Accurate vibrational energies and wave functions computed with incorporation of the geometric phase effect (via gauge theory) and using an ab initio potential energy surface were employed in this work. A sophisticated fully dimensional dipole moment function was constructed using accurate ab initio ca...
متن کاملNonspreading Wave Packets for Rydberg Electrons in Rotating Molecules with Electric Dipole Moments.
Nonspreading wave packets for Rydberg electrons are predicted in rotating molecules with electric dipole moments. We have named them the Trojan wave packets since their stability is due to the same mechanism that governs the motion of the Trojan asteroids in the Sun-Jupiter system. Unlike all previously predicted Trojan wave packets in atoms, molecular Trojan states do not require external fiel...
متن کاملWhistler modes with wave magnetic fields exceeding the ambient field.
Whistler-mode wave packets with fields exceeding the ambient dc magnetic field have been excited in a large, high electron-beta plasma. The waves are induced with a loop antenna with dipole moment either along or opposite to the dc field. In the latter case the excited wave packets have the topology of a spheromak but are propagating in the whistler mode along and opposite to the dc magnetic fi...
متن کاملComputational study of molecules for quadratic nonlinear optical applications : orthogonal orientation of dipole vector and hyperpolarisability pseudo vector
In pushÈpull organic molecules of interest in quadratic nonlinear optical (NLO) applications, the major hyperpolarisability component usually lies along the dipole axis. Most of these molecules crystallise with the dipole moment vectors of near neighbors aligned antiparallel, leading to near-cancellation of their hyperpolarisability tensor components and poor bulk NLO response. Appropriate desi...
