Abstract
The inducement of physical, chemical, structural and biological properties to entice of pharmaceutical property was analyzed by Vibrational spectroscopic, biological and theoretical tools. The structural arrangement for describing structure activity was investigated by injecting ligand groups in internal coordinate system by molecular tools (FT adopted IR, Raman, and NMR). Bond length and bond angle strain was pronounced much due to the chemical equivalent forces extension due to the injection of substitutional groups on base compound and thus non-Centro symmetry was processed. The molecular charge depletion profile was thoroughly studied to persuade protonic and electronic delocalization setup for arranging the drug potential. The chemi-equivalent potential exchange was monitored among different parts of the molecule for obtaining drug mechanism. The biological profile was keenly observed to look at the biological ambiance of the present molecule to fabricate advanced drug. The Lipinski five rule parameters; MV = 137.18, LogP = 0.27, HBD = 2, HBA = 2 and TPSA = 46.2 A2 showed the enhancement of additive drug quality. The exchange of oscillating chemical energy in the core and allied carbons of the base skeleton was keenly noted to find the prearranged chemical environment for successful drug mechanism. The non bonded transitions between Lewis acid and base of bonded molecular system were observed to determine the restoring potential to customize drug potential. The drug assistance for enantiomer characteristics of chirality sequence was displayed to expose the toxicity effect of the molecule. The active molecular bondings on different sites of molecule were measured by estimating polarizability and associated biological inhibition was validated.

Abstract
The molecular structural dimerization of biologically potent 2-chloro-5-fluoro phenol (2C5FP) is optimized. A combined experimental and theoretical characteristics of vibrational spectral determinations (NMR, FT-IR and Raman) on 2-chloro-5-fluoro phenol (2C5FP) were used at DFT-B3LYP/6–31++G (d,p) level of computation. A close coherence is achieved when experimentally observed wave numbers are compared with calculated wave numbers by refinement of the scale factors. Calculated values of global chemical descriptors of the present molecule reveal significant molecular stability and chemical reactivity. Non-Linear optical (NLO) property of the present molecule is investigated by determining the second order non linear parameter of first hyperpolarizability β. Moreover, hydrogen bond and thermodynamic parameters at various temperatures are determined and discussed. Investigated compound 2C5FP possesses a better antibacterial activity against Echerichia coli, Streptococcus aureus, Pseudomonas aureus,and Staphylococcus aureus, respectively. The title molecule is subjected to molecular docking studies with two different proteins, namely Staphylococcus aureus Tyrosyl-tRNA synthetase (PDB ID: 1JIL) and human dihydroorotate dehydrogenase (hDHODH) (PDB ID: 6CJF). The results of molecular docking analysis support the antibacterial activity and demonstrate a strong interaction with the DHODH inhibitor.

Abstract
In this attempt, in order to obtain high-quality NLO crystal, organic compound; 3-(3,4-Dihydroxyphenyl)-L-Alanine crystal was fabricated. The organic-composite crystal was characterized by crystallographic and spectroscopic tools. The NLO supported parameters like crystal lattice (orthorhombic) and space group (P212121) examined and validated by XRD examination. The SHG test was carried out and SHG efficiency was calculated that1.29 and 1.35 times greater than solid KDP crystal. The laser damage threshold energy density was determined to be 14.51 GW/cm2. By the application of mulliken charge assignment, multiple dielectric cavities were found in crystal material which is able to process the high degree of birefringence gradient. The oscillating chemical potential movement was observed by examining chemical shift, among the core carbons of hexagonal ring and bridge carbons of chain. The chemical softness insists the binding viability of further ligand groups. The π and δ-conjugated interactive complex orbitals recognized on molecular site and participation in optical active mechanism was identified. UV-Visible transmission characteristics of crystal were studied and UV-Visible absorption on degenerate energy states was noted and its band gap energy was estimated. The CT complex of the present case was acknowledged to be COOH group and it causing crystal properties of current organic composite. The hyperactive polarizability was determined as 1775.05 × 10-33 esu and it was found to be five times greater than thiourea. The depletion energy between highly electrophilic zones and protonic zones was estimated to be ±5.241 e 2 causing permanent dielectric characteristics for the title organic composite. The non-superposable on the molecular mirror image was displayed and thereby optical ability was validated.

The observed fundamental frequencies (IR and Raman) are assigned according to their distinctiveness region. The hybrid computational calculations are carried out by HF and DFT (B3LYP and B3PW91) methods with 6-31++G(d,p) and 6-311++G(d,p) basis sets and the corresponding results are tabulated. The impact of the presence of tri-chlorine atoms in phenyl structure of the compound is investigated. The vibrational sequence pattern of the molecule related to CH2COOH is analyzed. Moreover, (13)C NMR and (1)H NMR are calculated by using the gauge independent atomic orbital (GIAO) method with B3LYP methods and the 6-311++G(d,p) basis set and their spectra are simulated and the chemical shifts related to TMS are compared. A study on the electronic and optical properties; absorption wavelengths, excitation energy, dipole moment and frontier molecular orbital energies, are performed by HF and DFT methods. The Kubo gap of the present compound is calculated related to HOMO and LUMO energies which confirm the occurring of charge transformation between the base and ligand group. Besides frontier molecular orbitals (FMO), molecular electrostatic potential (MEP) was performed. NLO properties related to Polarizability and hyperpolarizability are also discussed.
