Abstract
Ethyl substituted para-hydroxybenzoate known as ethyl para-hydroxybenzoate (EHB) organic single crystal is grown by solvent controlled slow evaporation system with methanol as a solvent. The grown EHB crystal unit cell geometry is investigated using a single crystal XRD system. The Plasma, Fermi and Penn energy analyses also the molecular electronic polarizabilities are evaluated by different methods such as Clausius-Mossotti, coupled dipole method and Lorentz relations. The optical absorption and transmittance spectrum are assessed by UV–visible spectrum. The different optical constants as wavelength cut-off range, optical energy gap, extinction and absorption coefficient, refractive index, the position of conduction and valance band, optical electronegativity, nonlinear absorption coefficient, etc are calculated. The dielectric nature and molecular orbital analysis are evaluated. From the z-scan analysis, third-order nonlinear optical assets are estimated.
