The calculated IR and Raman spectra with their intensities, molecular electrostatic potential (MESP) surface and highest occupied molecular orbital (HOMO) - lowest unoccupied molecular orbital (LUMO) plot have been given. %K APTZ %K ab initio %K DFT %K IR %K Raman %K MESP %K HOMO-LUMO %U http://nepjol.info/index.php/BIBECHANA/article/view/7151
