| Abstract | In this study, a novel compound (S)-N-benzyl-1-phenyl-5-(thiophen-3-yl)-4-pentyn-2-amine (abbreviated as BPTPA) was synthesized and structurally characterized by FT-IR, NMR and UV spectroscopy. The molecular geometry and vibrational frequencies of BPTPA in the ground state have been calculated by using the density functional method (B3LYP) invoking 6-311++G(d,p) basis set. The geometry of the molecule was fully optimized, vibrational spectra were calculated. The fundamental vibrations were assigned on the basis of the total energy distribution (TED) of the vibrational modes, calculated with scaled quantum mechanics (SQM) method and PQS program. Total and partial density of state (TDOS and PDOS) and also overlap population density of state (OPDOS) diagrams analysis were given. The energy and oscillator strength of each excitation were calculated by time-dependent density functional theory (TD-DFT) results complements with the experimental findings. The NMR chemical shifts ((1)H and (13)C) were recorded and calculated using the gauge invariant atomic orbital (GIAO) method. The dipole moment, linear polarizability and first hyperpolarizability values were also computed. The linear polarizability and first hyper polarizability of the studied molecule indicate that the compound is a good candidate of nonlinear optical materials. Finally, vibrational wavenumbers, absorption wavelengths and chemical shifts were compared with calculated values, and found to be in good agreement with experimental results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
