    Notes: Abstract Describes a new method of evaluation of scientific output by laboratories engaged in diverse fields of research. This method helps to evaluate those outputs which are quite recent and not amenable to citation analysis. For the purpose of analysis, impact factor of journals in which papers are published are considered. A method for normalisation of impact factor of journals has been described and, normalised impact factors have also been used for the purpose of analysis. It is found that in such analysis normalised impact factor tends to show better results compared to simple impact factor. The analysis helps us to generate numerous performance indicators such as average impact factor and normalised impact factor for each laboratory and the research complex such as CSIR as a whole; average impact factor and normalised impact factor for each scientist of a laboratory and the research complex; spectral distribution of papers falling within various ranges of impact factors and normalised impact factors. By comparing the performances over several years the trend of research activity of each laboratory can also be obtained.

    Indian periodicals in the science citation index (1992)
    Springer

    Notes: Abstract The coverage of Indian S&T periodicals inSCI has been studied covering the period 1975–88. The study shows that coverage is rather poor due to a variety of reasons. Many of the Indian periodicals do not fulfil the criteria for getting covered inSCI. About 500 periodicals have been identified which are covered by at least one major indexing or abstracting service of the world. Total number of such periodicals is likely to be over 600. Slight improvement in the standard of these periodicals is likely to make many of them worthy of coverage bySCI.

    Description / Table of Contents: Nitrosylrhenium-Komplexe: Synthesen, Eigenschaften und Strukturen von OxalatoderivatenDie freie Säure H[Re(NO)(C2O4)(OH)2H2O] wurde durch Umsetzung von Re(NO)(OH)3 = H2O mit Oxalsäure in wäßrigem Medium erhalten. Die K+-, NH4+- und Pb2+-Salze der Säure wurden isoliert sowie nichtelektrolytische Diimino-Derivate, Re(NO)(C2O4)X = L (X = 1, 10-Phenanthrolin-2,2′-Dipyridyl; L = OH-, Cl-) synthetisiert. Die Komplexe werden elementaranalytisch, spektroskopisch (UV-VIS, IR), magnetisch und durch Leitfähigkeitsdaten charakterisiert und ihre Strukturen vorgeschlagen.
    Notes: The free acid, H[Re(NO)(C2O4)(OH)2(H2O)] has been prepared from the reaction of Re(NO)(OH)3 = H2O with oxalic acid in aqueous medium. The K+, NH4+ and Pb2+ salts of the acid have been isolated. Nonelectrolytic diimino derivatives, Re(NO)(C2O4)X · L (X = 1, 10-phenanthroline, 2,2′-dipyridyl; L = OH-, Cl-) have been synthesized. The complexes have been characterised through elemental analyses, spectral (u.v., vis., i.r.) properties, magnetic and conductance data and their structures are proposed.

    Description / Table of Contents: Nitrosyl-Rhenium-Komplexe: Iodonitrosyl-DerivateRe(NO)I52- wurde als Cs+- Rb+- und dipyH+-Salz isoliert. Außerdem wurden das nicht elektrolytische Re(NO)I3L (L = 1,10-Phenanthrolin und 2,2′-Dipyridyl) und [Re(NO)IL2]PtCl6 dargestellt. Aus einer Lösung von Re(NO)(OH)3 in HI wurde eine Verbindung der Formel Re(H2O)(NO)(OH)I2 isoliert, deren Pyrolyse Re(H2O)0.5(NO)(OH)2I ergab. Bestimmung der elektronischen und IR-Spektren sowie der magnetischen Momente wurde durchgeführt. Die Eigenschaften der Iod-Derivate werden mit den entsprechenden der Fluor-, Chlor- und Brom-Komplexe verglichen.
    Notes: The anionic Re(NO)I52- has been isolated as salts of Cs+, Rb+, and dipyH+. The nonelectrolytic Re(NO)I3L (L stands for 1,10-phenanthroline and 2,2′-dipyridyl) and cationic [Re(NO)IL2]PtCl6 have also been prepared. From a solution of Re(NO)(OH)3 in HI, compound of formula Re(H2O)(NO)(OH)I2 has been isolated, pyrolysis of which yielded Re(H2O)0.5(NO)(OH)2I. Measurements of electronic and i.r. spectra and magnetic moments have been carried out. The properties of the iodo derivatives have been compared with those of the corresponding fluoro, chloro and bromo complexes.
