| Abstract | Intermolecular cation exchange between sodium iodide and sodium benzophenone and sodium naphthalene ion pairs in THF has been studied by e.s.r. linewidth measurements. For sodium benzophenone the plot of the reciprocal lifetime of a sodium spin state against sodium iodide concentration is markedly curved and not linear as would be expected if the exchange takes place in a single bimolecular reaction step. A mechanism which explains the curvature has been suggested in which the exchange involves an equilibrium between the two ion pairs and a dipole–dipole association ion quadruplet. The change in spin state of the sodium coupled to the benzophenone anion takes place by an internal re-arrangement in the ion quadruplet. Values for the equilibrium constant and for the velocity constant of the re-arrangement have been obtained. The reciprocal lifetime plot for sodium naphthalene is approximately linear and a value for the velocity constant for the bimolecular exchange reaction step has been obtained. |

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.
