| Abstract | Using the first-principles real-space finite-difference method, we have theoretically examined optimized structures and electronic energy levels of three peanut-shaped C120 molecules (C60 dimers), namely, P55-, P56-, and P66-C120 molecules. Our calculations show that as the number of eight-membered rings included in each C120 molecule increases, the total energy becomes large and the highest occupied molecular orbital–lowest unoccupied molecular orbital (HOMO–LUMO) energy gap becomes small. For the P56-C120 molecule, the LUMO is found to be localized at one C60 component, while for the other molecules, the LUMOs are extended over the entire molecule. This fact is understood from the symmetry/asymmetry in the atomic configuration of the three C120 molecules. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
