Abstract

The experimental spectroscopic investigation of N-benzyloxycarbonyloxy-5-norbornene-2,3-dicarboximide (C 17 H 15 NO 5 ) molecule has been done using 1 H and 13 C NMR chemical shifts, FT-IR and Raman spectroscopies. Conformational forms have been determined depending on orientation of N-benzyloxycarbonyloxy and 5-norbornene-2,3-dicarboximide (NDI) groups of the title compound. The structural geometric optimizations, vibrational wavenumbers, NMR chemical shifts (in vacuum and chloroform) and HOMO-LUMO analyses for all conformers of the title molecule have been done with DFT/CAM-B3LYP method at the 6-311++G(d,p) basis set. Additionally, based on the calculated HOMO and LUMO energy values, some molecular properties such as ionization potential (I), electron affinity (A), electronegativity (χ), chemical hardness ( h ), chemical softness ( z ), chemical potential (μ) and electrophilicity index ( w ) parameters are determined for all conformers. The non-linear optical (NLO) properties have been studied for the title molecule. We can say that the experimental spectral data are in accordance with calculated values.
