Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>New organic DL-alanine maleate single crystals have been grown using slow evaporation solution growth technique. The solubility of grown material was determined using water as solvent. Single crystal X-ray diffraction reveals that the grown crystal crystallises in orthorhombic system with non-centrosymmetric space group. Functional groups and their modes of vibration were studied by Fourier transform infrared and Raman spectrum. Thermal stability and nature of decomposition were studied using thermogravimetric analysis/differential thermal analysis plot. The grown crystal shows low absorption behaviour in the entire visible region. A dielectric study was also a study of the distribution of charges within the crystal. Non-linear optical property of the crystal was confirmed using the Kurtz and Perry powder technique.</p> </abstract>
