The ability to correlate a spectrum to a precalibrated chart accurately (to within 0. 02 ppm) has made chemical shift, along with the character of the spectral lines produced, an increasingly important tool in configurational analysis-a tool which this book is designed to complement. It is known that the chemical shift of a proton can be influenced by atoms as much as five or six carbons away, a fact of great importance to compound identification. The entries in this book, arranged according to proton environment, enable the researcher with a hypo thetical structure already proposed for his unknown quickly to locate examples of compounds having similar structures. An index of molecular formulas and a shift index, which should prove useful in hypothesizing alternate structures for the unknown and in checking out the hypotheses, have also been provided. The data collected represent some 4800 shifts from the spectra of about 1200 compounds that appear in the ca | | 出版日期 | Book 1968 | | 关键词 | Atom; NMR; Pet; atoms; development; environment; influence; iron; nuclear magnetic resonance (NMR); spectra; s | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4684-7296-7 | | isbn_softcover | 978-1-4684-7298-1 | | isbn_ebook | 978-1-4684-7296-7 | | copyright | Springer Science+Business Media New York 1968 |
