“…TABLE- Non-linear optical (NLO) properties: The non-linear optical (NLO) effects arise from the interactions of electromagnetic fields in various media to produce new fields altered in frequency, amplitude, phase or other propagation characteristics from the incident fields. Non-linear optical is at the forefront of present research because of its importance in providing the key functions of optical modulation, frequency shifting, optical switching, optical logic and optical memory for promising technologies in the areas such as signal processing, telecommunications and optical interconnections [30][31][32][33]. The dipole moment (µ), polarizability (α) and second-order polarizability or the first hyperpolarizability (β), are calculated using DFT with 6-31+G(d,p) and 6-311++G (d,p) basis sets on the basis of the finite-field approach.…”

In present work, the ultraviolet absorption spectrum of tetrahydroxy-1,4-quinone hydrate (TH,1,4-QH) has been carried out experimentally (in water, methanol dimethyl sulfoxide, acetonitrile and chloroform) and theoretically in the range 3500-2300 cm -1 in the solution phase. Predicted electronic absorption spectra from time dependent density functional theory (TD-DFT) calculation have been analyzed and compared with the experimental UV-visible spectrum. The effects of hydroxy group substituent in benzoquinone ring have been analyzed. The electronic properties such as excitation energy, wavelength corresponding to absorption maxima (λmax), oscillator strength (f), HOMO and LUMO energies are calculated by time-dependent density functional theory (TD-DFT) using HF/6-311++G(d,p) and B3LYP/6-311++G(d,p) as basis sets. The electric dipole moment (µ), α (polarizability) and β (first hyperpolarizability) have been computed to evaluate the NLO (non-linear optical) response of the investigated compound by Hartree-Fock (HF) and density functional theory (DFT) with B3LYP basis sets. Mulliken atomic charges of the atoms are calculated by DFT (B3LYP). In addition natural bond orbital (NBO) analysis has been done using TD-DFT with B3LYP/6-311++G(d,p) basis sets.

“…Such materials find application in technologies such as optical computing and optical communication [2,3]. Recently, much focus has been given to organic NLO materials for applications in field of photonics [4] due to their large nonlinear response, good optical limiting behavior, fast switching time, and convenient optimization routes through molecular design compared to the currently used inorganic materials [5]. Chalcone derivatives are one of the interesting groups of materials as they are exhibiting high NLO coefficients and good crystallizability [6].…”

Single crystals of 1-(5-chlorothiophen-2-yl)-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one (CTTMP) having nonlinear optical property have been grown by slow evaporation technique. The functional groups were identified by FT-IR and NMR techniques. The mechanical property of the crystals was studied using Vicker's microhardness tester and the load dependence hardness was observed. The material is dimensionally stable up to 112 ∘ C. The dielectric properties of the crystals were determined using semiconductor characterization system. The optical limiting behavior of the crystal was studied using Z-scan technique.

“…(Phillips, 1968;Phillips & Van Vechten, 1969;Van Vechten, 1969) and the bond-charge model (Levine, 1973a, b) are the basis of numerous calculations of diverse optical phenomena (see e.g. Chemla, 1980;Shih Chun-Ching & Yariv, 1982;Tsirelson, Korolkova, Rez & Ozerov, 1984;Kucharczyk, 1987a;Sangwal & Kucharczyk, 1987). The starting point for all the calculations is Penn's nearly-free-electron model of the dielectric constant at long wavelengths (Penn, 1962) …”

ELECTRON DENSITY IN CHROMIUM SULFATE PENTAHYDRATECu(1) and 1.06 (7) e for Cu(2)] are greater than the corresponding values for CrSOa.5H20 [a mean value of 0.10 (4)e for the ligating water molecules, and 1.1 (2) and 0.7(2) e for the Cr(1).4H20 and Cr(2).4H20 moieties respectively].The average charges on the sulfate O atoms are comparable for the two structures, being -0.30 (3) e for CrSO4.5H20 and -0.32 (1)e for CuSOa.5H20. However, the agreement between the individual charges on the sulfate O atoms does not compare so favourably, indicating a need for caution when interpreting individual charges.Calculations were performed on a Perkin-Elmer 3240 computer using programs from the XTAL system (Stewart & Hall, 1985). We thank C. Chantler for use of the program PARTN, which is compatible with the XTAL system. We also thank B. W. Skelton for providing the X-ray data. AbstractThe ionic radii providing the observed optical susceptibilities in alkali halides have been determined. The result is the set of crystal radii ra ~-0'78, 0.91, 0.92, 0
