Working overseas, | The Field of Technical Writing 11 The new approach based on nuclear magnetic resonance NMR spectroscopy chemical shifts is faster and simpler than conventional NMR methods. Typically NMR protein structures are based on interatomic distances but these are difficult to measure. On the other hand chemical shifts are the most readily obtained and accurate NMR parameters. They provide information about the molecular environment of atoms. They re used to determine structures of small molecules and they re usually the first thing chemistry undergrads learn about NMR. Researchers have wanted to use chemical shifts to determine protein structures because that sidesteps the need to make timeconsuming nuclear Overhauser effect NOE measurements. NOEs which are pairwise distances between specific atoms are currently the primary basis for most NMR protein The article in example two appeared in Chemical and Engineering News a member-supported weekly magazine of the American Chemical Society. This publication and online resource covers all the news of the chemical world including recent advances in research industry education funding and regulations. The article was written by a staff correspondent who specializes in biochemistry medicinal chemistry analytical chemistry organic chemistry and combinatorial chemistry. Those who write for the magazine must be able to handle highly complex ideas and terms and still be able to write an interesting story that is easy to understand. The author of this particular article does have one distinct advantage most of his readers are chemists. Nevertheless few of them will have detailed knowledge about the field of work being described. 2. Borman Stu. Fast Route to Structures Technique Defines Protein Structures from NMR Chemical Shifts.
