|Abstract||Radiation generated by stimulated Raman scattering (SRS) in H/sub 2/ at liquid N/sub 2/ temperatures was evaluated as a tunable, sharp-line, ultraviolet laser source for the excitation of atomic fluorescence of those elements, such as As, Se, Te, and Zn, whose resonance excited states are usually more than 40,000 cm/sup -1/ above the ground state. To populate these states requires primary radiation of wavelengths that are shorter than can be provided by laser-frequency doubling techniques. These wavelengths are within the range that can be reached through stimulated Raman scattering of dye-laser primary radiation. In the studies described, a YAG pumped, dye-laser source provided the primary radiation that was scattered in the SRS cell into Stokes and anti-Stokes components. Data on the analytical figures of merit are presented and compared with those obtained by conventional inductively coupled plasma atomic emission spectroscopy and hollow-cathode lamp excited atomic fluorescence spectroscopy.|

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.
