Resonant Optical Rectification in Chiral Molecular Systems: Application to a Three-level Mode
نویسنده
چکیده
Linear and nonlinear interactions of an electromagnetic wave with molecules of an isotropic medium induce in them multipole moments which contribute to electric polarization of the system [1]. Out of absorption bands optical rectification (OR) via the second-order susceptibility is forbidden but the fourth-order dipolar electric nonlinearity may cause OR in chiral liquids [2]. However, in absorption bands of optically active molecular system OR is allowed via the imaginary part of the Second-order susceptibility related to electric dipole interaction with the radiation field [3]. We consider an isotropic molecular system in which a plane monochromatic light wave with the electric field

Numerical Calculation of Resonant Frequencies and Modes of a Three-Atom Photonic Molecule and a Photonic Crystal in an External Cavity
In the present paper, resonant frequencies and modes of a three-atom photonic molecule and a photonic crystal placed within a cavity are numerically calculated. First, governing formulation in transverse electric field mode (TE) is obtained using Maxwell equations. Then, an algorithm based on a finite difference scheme and matrix algebra is presented. The algorithm is then implemented in a comp...
متن کاملApplication of Guanidine Hcl to Improve Enantioseparation of a Model Basic Drug, Cetirizine, By Capillary Electrophoresis Using Sulfated Β-Cyclodextrin
A common approach in resolving enantiomers of chiral basic drugs by capillary electrophoresis (CE) is to use cyclodextrins (especially their anionic derivatives) as chiral selector in the acidic buffer (pH ≤ 3) in normal or reversed (carrier) mode. Then, some organic modifiers are added to the buffer solution if the resolution is not satisfactory. In case of cetirizine (CTN), applying the same ...

متن کاملTheoretical study of magnetic susceptibility and optical activity of small molecules containing one chiral center
In the first part of this work, correlation between optical activity and elements of magnetic susceptibility tensor (MST) for five classes of model small molecules containing a single chiral center has been studied using quantum computational techniques at DFT-B3LYP level of theory with 6-311G basis set. Several molecular properties are used to reduce the MST elements prior to the examination o...
متن کاملOptical Chirality Enhancement in Twisted Arrays of Plasmonic Nano-rods
An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...
