The synthesis, spectroscopic (IR, H-1 and C-13 NMR chemical shifts) investigations of 2,2'-Dicarboxy-4,4'-(propane-2,2-di-yl)diphenol molecule have been confirmed. Molecular geometry, vibrational frequencies and gauge including atomic orbital (GIAO) H-1 and C-13 NMR chemical shift values of the compound in the ground state have been calculated using the density functional method (OFT) with 6-311G++(d,p) basis set. The calculated values are in good agreement with the experimental values. The energetic behavior of the compound in solvent media has been examined using B3LYP method with the 6-311G++(d,p) basis set by applying the polarizable continuum model (PCM). The total energy of the compound decreases with increasing polarity of the solvent. Besides, molecular electrostatic potential (MEP), non-linear optical (NLO) properties of the compound have been investigated by using theoretical calculations. (C) 2014 Elsevier B.V.
