| Abstract | The spectroscopic properties were investigated by FT-IR, FT-Raman and (1)H and (13)C nuclear magnetic resonance (NMR) techniques. The FT-IR (4000-400cm(-1)) and FT-Raman (3500-100cm(-1)) spectra in the liquid phase were recorded for 4,4-dimethyl-2-oxazoline (abbreviated as DMOZ). The (1)H and (13)C NMR spectra were recorded and chemical shifts were calculated by using the gauge independent atomic orbital (GIAO) technique with DFT/B3LYP/6-311++G(d,p) basis set and compared with experimental results. The structure of the compound was optimized and quantum chemical calculations of energies, geometric parameters (bond lengths and bond angles) and vibrational wavenumbers of DMOZ were carried out using DFT/B3LYP method with 6-311++G(d,p) basis set. Temperature dependence thermodynamic parameters and magnetic properties of the title compound have been analyzed. The dipole moment (µ), polarizability ( ¯), anisotropy polarizability (γ(2)) and hyperpolarizability (ßtot) of the molecule have been reported. Stability of the molecule arising from hyper conjugative interactions and charge delocalization has been analyzed using natural bond orbital (NBO) analysis. The energy and oscillator strength were calculated using absorption spectra (UV-Vis spectrum), this spectral analysis confirms the charge transfer of the molecule. A study on the electronic properties, such as HOMO and LUMO energies, molecular electrostatic potential (MEP) were also performed. |

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.
