|Abstract||The Platt electrostatic model for calculating equilibrium internuclear distances and force constants of diatomic hydride molecules was used to calculate properties of diatomic hydride ions. An empirical approach to the scaling technique was employed in order to render the model consistent with the quantum mechanical virial theorem. This has the additional advantage of improving the calculated equilibrium properties. For twelve known hydride ions there is satisfactory agreement between calculated and experimentally measured force constants and equilibrium internuclear distances. The applicability of the relation Kr/sub e//D/sub o/ = const. to a sequence of similar diatomic ions was briefly examined. Calculated values of K and r, were used in the above relation to estimate dissociation energies of the rare-gas hydride ions. Results are compared with experimental limits determined from mass spectrographic investigations. Equilibrium properties of the corresponding neutral species calculated by the Platt electrostatic model are consistent with the generally assumed instability of the rare gas hydride molecules.

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
