Get this from a library. Polarized crystal spectra of optically active ions. [Robert B Dingle; Carl Johan Ballhausen]. Polarized crystal spectra are reported for the trans‐[Coen 2 Cl 2] + ion and the trans‐[Co(1‐pn 2 Cl 2] + ion in various crystals at temperatures down to 25°K. The spectra are analyzed in terms of several vibronic intensity gaining by: Add tags for "Polarized crystal spectra of optically active ions / 2, Cobalt tris ethylenediamine ion.".

BALLHAUSEN København Kommissionær: Munksgaard. Synopsis The polarized absorption spectra of d,lCoenaCH2 0, d,l[Coen3 Cla]2 0 and D[GoenaCl3] 2 0 and the deuterated species have been recorded at liquid helium.

The polarized optical absorption and emission spectra of the crystal have been investigated. The Yb3+:LiLa(MoO4)2 crystal has a broad absorption FWHM of 29 nm at nm. Polarized Raman scattering spectra of the NaY(WO 4) 2 (NYW) single crystal have been measured.

Its structure is described in the tetragonal space group isomorphic to CaWO 4 scheelite. The A g, B g and E g spectra were made and discussed in terms of factor group analysis. These spectra are compared to those of monoclinic KY(WO 4) 2 (KYW) single crystals whose structure differs from.

The electronic structure of Eu 3+ ions doped in YAl 3 (BO 3) 4 crystal are investigated by means of room temperature absorption and emission spectroscopy in –30, cm −1 range. The observed transitions are assigned and analyzed on the basis of group theory assuming that Eu 3+ ion occupies a D 3 symmetry site.

Eu 3+ Free-ion energy diagram is presented and the. Optical rotation or optical activity (sometimes referred to as rotary polarization) is the rotation of the plane of polarization of linearly polarized light as it travels through certain materials as shown below.

The materials that can do so are called optically active materails. Optical activity occurs only in chiral. The cubic-phase CsPbBr 3 crystal is made up of PbBr 6 − octahedral structures (drawn in pink) and Cs + ions.

Stress along the shear interface resulted in screw dislocation perpendicular to the. Low‐temperature polarized crystal spectra of the [V(urea) 6] 3+ ion are presented and discussed. In many ways they closely resemble those seen in V 3+ /Al 2 O ground‐state splitting of 3 A 2 has been established by both optical and magnetic means and is reported as ± cm − source of spectral intensity is almost entirely due to the influence of the static, odd crystal.

The polarized absorption spectra of the Nd 3+ ion in optically active single crystals of Na 3 Gd(diglycolate) 3 2NaClO 4 6H 2 O have been measured in the nm spectral range over the temperature range from 4 to K using spectrographic and spectrophotometric methods.

Pulsed Zeeman measurements of selected spectral regions have also been performed. The analysis of broad bands in the polarized electronic spectra of transition metal ions in crystals is discussed. The band of cobalt(III) acetylacetonate due to the transition 1T1←1A1 is found to be split by the trigonal field into components at 16 cm—1 (1A2) and at 17 cm—1 (1E).

The spectra indicate that the trigonal field of the free molecule is not appreciably distorted in. Surface-enhanced Raman optical activity offers potential capabilities for sensitive, rapid, stereochemical characterization of basic building blocks of biopolymers, such as amino acids and nucleosides, as well as biologically active molecules, in particular, also for probing organization and self-assembling of such molecules on metal surfaces.

In the optical absorption spectra of Ti:Al 2 O 3 crystal doped with higher concentration of titanium and annealed with hydrogen, in addition to the main absorption band of T i A l 3 + ( nm, nm), a small absorption band of nm and a concomitant small bump on the short-wave side of the nm absorption band was often observed.

The measured high coupling strength between a single photon and the ion allows for optical Rabi oscillations and a high coupling cooperativity, which could enable optically controlled spin .We introduce excitonic polarized photoluminescence (PL) of nonpolar ZnO layers and related quantum well (QW) structures in terms of crystal symmetries and lattice distortions.

Polarized PL characters are attributed to in-plane anisotropic strains in the host, which are fully demonstrated on A-plane ZnO. Theoretical evaluations propose that in-plane compressive strains induced in ZnO layers.
