Theoretical Studies of Structure, Spectroscopy, and Properties of a New Hydrazine Derivative

الملخص EN

We will report a combined experimental and theoretical study on molecular structure, vibrational spectra, and energies of (E)-1-(2,4-dinitrophenyl)-2-[(4-methylphenyl)methylidene]hydrazine (1).

The molecular geometry and vibrational frequencies and energies in the ground state are calculated by using HF and DFT levels of theory with 6-311G basis sets.

The calculated HOMO and LUMO energies also confirm that charge transfer occurs within the molecule.

The harmonic vibrational frequencies were calculated, and the scaled values have been compared with experimental FTIR and FT-Raman spectra.

The observed and the calculated frequencies are found to be in good agreement.

The experimental spectra also coincide satisfactorily with those of theoretically constructed bar-type spectrograms.
