Investigation of Some Theoretical Properties of 1-Methyl-3-phenyl-4-[3-(pnitrobenzoxy)benzylideneamino]-4,5-dihydro-1H-1,2,4-triazol-5-one

Öz

In this study, 1-methyl-3-phenyl-4-[3-(p-nitrobenzoxy)benzylidenamino]- 4,5-dihydro-1H-1,2,4-triazol-5-one was optimized by using the B3LYP/6-31G(d) and HF/6-31G(d) basis sets. 1H-NMR and 13C-NMR isotropic shift values were calculated by the method of GIAO using the program package Gaussian G09W. Experimental and theoretical values were inserted into the grafic according to equatation of δ exp=a+b. δ calc. The standard error values were found via SigmaPlot program with regression coefficient of a and b constants. IR absorption frequencies of this compound were also calculated by two methods. The Veda4f program was used in defining IR data which were calculated theoretically. Furthermore, bond angles, bond lengths, Mulliken atomic charges, HOMO-LUMO energies, dipole moments, total energies of 1-methyl-3- phenyl-4-[3-(p-nitrobenzoxy)benzylidenamino]-4,5-dihydro-1H-1,2,4-triazol-5-one have been investigated.
