Tuned Range-Separated Time-Dependent Density Functional Theory Applied to Optical Rotation.

Journal of Chemical Theory and Computation, 2012
For range-separated hybrid density functionals, the consequences of using system-specific range-separation parameters (γ) in calculations of optical rotations (ORs) are investigated.

Time-dependent density functional theory for calculating origin-independent optical rotation and rotatory strength tensors.

ChemPhysChem, 2011
An approach to calculate origin-independent electronic chiroptical property tensors using time-dependent density functional theory (TDDFT) and gauge-including atomic orbital (GIAO) basis sets is evaluated.

Optical rotation calculated with time-dependent density functional theory: the OR45 benchmark.

Journal of Physical Chemistry A, 2011
Time-dependent density functional theory (TDDFT) computations are performed for 42 organic molecules and three transition metal complexes, with experimental molar optical rotations ranging from 2 to 2 × 10(4) deg cm(2) dmol(-1).

Selective trapping or rotation of isotropic dielectric microparticles by optical near field in a plasmonic archimedes spiral.

Nano letters (Print), 2014
We demonstrate selective trapping or rotation of optically isotropic dielectric microparticles by plasmonic near field in a single gold plasmonic Archimedes spiral. Depending on the handedness of circularly polarized excitation, plasmonic near fields can

Chemical distinction by nuclear spin optical rotation.

Physical Review Letters, 2010
Nuclear spin optical rotation (NSOR) arising from the Faraday effect constitutes a novel, advantageous method for detection of nuclear magnetic resonance, provided that a distinction is seen between different chemical surroundings of magnetic nuclei ...

The optical rotation of gelatin films

Journal of Polymer Science Part A-1: Polymer Chemistry, 1968
AbstractOptical rotation measurements of a series of relatively thick gelatin films prepared under a variety of drying conditions were made. The technique permits rotation measurements to be made during the drying process. It is found that the temperature and humidity of the drying air do not significantly affect the rotation of the films at ...

Rotation of the Moon; Optical Librations

1966
The revolution of the Moon around the Earth, and with the Earth around the Sun, are not the only motions performed by our satellites. As has been realized in the earliest days of lunar observations from the fact that the Moon exhibit to us on Earth (almost) always the same face, it must also rotate with a uniform angular velocity about an axis fixed in
