    Publications Authored by Bar-Ilan Chemists Top List of "Most Read Articles" in Two Prestigious Scientific Journals

    Two groundbreaking publications by Bar-Ilan University investigators and their US colleagues – one from nearly 20 years ago and a second published seven years ago -- continue to top the list of the "most read articles" in two of the world's most prestigious scientific journals in chemistry.

    The first article, "NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities", was published on October 17, 1997 in the Journal of Organic Chemistry. In the article, Dr. Hugo Gottlieb, Dr. Vadim Kotlyar and Prof. Abraham Nudelman, of the Department of Chemistry, presented useful data for solving a day-to-day problem, namely the identification of trace residues of organic solvents in the routine use of nuclear magnetic resonance (NMR) as an aid for organic chemistry.

    The data presented in the article are downloaded on a virtual daily basis and have become invaluable to organic chemists worldwide and anyone experimenting with NMR analysis. Furthermore, the data have been attached to large numbers of NMR instruments worldwide and have been incorporated into major catalogs and manuals by the manufacturers of NMR instruments.

    The data will continue to be of value to future students and all those involved in NMR, and is therefore expected to remain in "most read" status for years to come.

    In addition, a second article expanding on the data was published in the journal Organometallics in 2010. The article, entitled "NMR Chemical Shifts of Trace Impurities: Common Laboratory Solvents, Organics, and Gases in Deuterated Solvents Relevant to the Organometallics", was a joint publication of investigators from the University of Washington and California Institute of Technology (Caltech), in collaboration with Gottlieb and Nudelman.

    The Journal of Organic Chemistry and Organometallics are considered top journals in their field. Both are published by the American Chemical Society.
