“…e search revealed fifteen (15) crystal structures bearing the phenol moiety, one 2CPH, and four (4) structures bearing 2APH. Crystals structures with the following reference codes were then chosen: PHENOL03 [20] with z′ � 3, WANMUU [21], z′ � 3, and AMPHOM02 [22] with z′ � 1. ere was, however, no crystal structure of 2NPH in the CSD as at the time of preparing this manuscript. e structures were visualized using version 3.9 of the CSD program Mercury.…”

The electronic spectra of phenol, 2-chlorophenol, 2-aminophenol, and 2-nitrophenol have been studied both experimentally and computationally. The effect of the substituents on the solvatochromic behavior of the phenols were investigated in polar protic (methanol) and aprotic (dimethyl sulfoxide (DMSO)) solvents. The spectra of 2-nitrophenol recorded the highest red shift in methanol. The observed spectral changes were investigated computationally by means of density functional theory (DFT) methods. The gas phase compounds were fully optimized using B3LYP functionals with 6-31++G(d,p) bases set. The effects of the substituents on the electron distribution in the σ-bonds as well as the natural charge on the constituent atoms were analyzed by natural bond orbital (NBO) and natural population analysis (NPA). Second-order perturbation analyses also revealed substantial delocalization of nonbonding electrons on the substituents onto the phenyl ring, thereby increasing its electron density. Full interaction map (FIM) also showed regions of varying propensities for hydrogen and halogen bonding interactions on the phenols.

NLO active 2-aminopyridinium 4-aminobenzoate (APAB) single crystals were successfully grown by the standard slow evaporation technique. The crystallinity of the grown crystals was analyzed through X-ray diffraction (XRD) measurements. Fourier transform infrared (FT-IR) spectroscopic studies were also performed for the identification of different modes present in the compound. The UV-Vis absorption and transmittance spectra were recorded for the grown crystal and the optical band gap was calculated. Birefringence and etching studies were also carried out. The dielectric study showed that the dielectric constant decreased with an increase in frequency. The photoconductivity study revealed its positive photoconducting nature. Theoretical HOMO LUMO investigations were also made for the crystal. The relative SHG efficiency of the material was investigated by the Kurtz and Perry powder technique. The phase matching property of the crystal was studied through the SHG dependence of average particle sizes.

“…In recent years, the demand for organic nonlinear optical material has been drastically increased because of their potential application in optoelectronic applications, such as optical switches, ultrafast electro-optic modulators, second harmonic generation, frequency mixing and laser spectroscopy [1][2][3][4]. Particularly, materials with aromatic rings have focused much attention because of their large hyperpolarizability (β), high electronic susceptibility (χ(2)), low cost, high resistance to laser damage, fast response time, ease of synthesis and device fabrication [5][6][7]. L-tartaric acid is a small organic molecule having large dipole moment, wide transparency range and chiral structure, to form noncentrosymmetric hydrogen bonded crystal structures -an important class of materials exhibiting interesting dielectric, ferroelectric, piezoelectric properties and optical second harmonic generation.…”

An organic single crystal of 4-chloroanilinium hydrogen (2R,3R)-tartrate monohydrate (4CAHT) was grown by slow evaporation solution growth technique at room temperature. Single crystal XRD study confirmed that the crystal belongs to monoclinic system with the space group P2 1 . Powder XRD analysis confirmed the crystalline nature of the compound. The presence of various functional groups in the compound was revealed by FT-IR analysis. UV studies showed the absence of absorption in the entire visible region. To determine the thermal stability of the grown crystals it was subjected to thermogravimetric and differential thermal analyses. Microhardness and etching studies were also carried out for the crystal. The powder second harmonic generation efficiency of 4CAHT was tested by Kurtz and Perry powder technique and the relative SHG efficiency of 4CAHT was found to be 1.44 times greater than that of standard KDP.
