| چکیده | ||
| In the present paper, we have reported the most suitable DFT methods to investigate the electro-optical properties of the liquid crystal molecules. Hybrid as well as meta GGA functional like ωB97XD, M06 and PBE0 are often used to optimize and calculate the various physical, thermal and optical parameters of the molecule. These functional are often used due to their good accuracy with experimental results. The 6-311G** basis set with 22 DFT methods was used to optimize and analyse the physical as well as optical properties of the liquid crystal molecule. The theoretical results obtained by density functional theory methods found in good agreement with experimental results of the molecule. | ||
