| Abstract | Much progress, both in experiment and theory, has been made in recent years for the small clusters of helium and molecular hydrogen containing a single guest molecule. Such studies allow the cluster properties to be determined with “atomic resolution” thus probing the onset of microscopic superfluidity. The rotational spectra of the He-CO and $H_{2}-CO$ complexes and small $He_{n}-CO$ (n ≤ 10) clusters, produced using a molecular jet expansion, were observed with intracavity millimeter-wave spectrometer (80-150 GHz). The key element of the spectrometer is a tunable oscillator, called OROTRON, which generates the millimeter-wave radiation through the interaction of an electron beam with the electromagnetic field of an open Fabry-Perot resonant cavity. Owing to the small dimensions of the resonant absorption cell, the OROTRON spectrometer is very suitable for double resonance experiments. The overview of the spectrometer as well as recent results on molecular complexes and small clusters will be presented. |

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.
