| Abstract | Among the compounds examined, intermolecular charge-transfer spectra are demonstrated for π-donors with sulphuryl chloride, selenium hexafluoride, tellurium hexafluoride, perchloryl fluoride, iodine heptafluoride, iodine oxide pentafluoride, ruthenium tetroxide, and osmium tetroxide. Colours of many of the two-component mixtures vanish when frozen, and the selenium and tellurium hexafluorides in p-xylene (m.p. 13 °C) effervesce and expel the acceptor into the vapour phase. The spectra define extremely weak interactions in the solvents carbon tetrachloride or cyclohexane, although in some cases the systems are too reactive for convenient quantitative study, whereas the precision of measurement is low for the volatile hexafluorides. For the same molar concentrations, selenium and tellurium hexafluorides produce nearly identical spectra with respect to wavelength position and small absorptivity values. Both show broad structureless absorptions at the 220 nm region for solutions in cyclohexane which are not observed in carbon tetrachloride or perfluoromethylcyclohexane and these are ascribed to hydrocarbon to MF6 intermolecular charge-transfer transitions. |

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.
