| Abstract | The second moments of cis- and trans-dichlorotetra-amminecobalt(III) chloride have been obtained between 77 and 300 K from CW spectra. Spin-lattice relaxation times for the trans isomer and “null times” for the cis isomer have been obtained between 77 and 440 K from pulse spectrometer measurements. The results suggest that in the trans complex one of the ammine ligands is unique, reorienting more slowly at a given temperature than the others, but that in the cis complex all the ammine ligands have about the same reorientation frequency at a particular temperature. Whole ion rotation occurs in the trans isomer, apparently about two different axes at two different crystal sites. Although whoel ion rotation, with a frequency which would narrow the n.m.r. line, does not occur in the cis isomer, libration does, and the second moment of the cis compound is interpreted in terms of such a torsional oscillation. |

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.
