FORMATION, CHARACTERISATION AND COMPUTATIONAL STUDY OF SOME 1,3-THIAZINES COMPOUNDS.

1,3-thiazines were synthesised using Schiff base and 3-mercaptopropanoic acid and characterised. Using the Gaussian 09W program, the current investigation utilised the Hartree-Fock approximation (HF) to compute diverse molecular characteristics, comprising optimisation, hardness, EHOMO, ELUMO, and energy gap, for a collection of synthesised molecules.
