Journal articles, Methods section materials, describing

The Introduction section of a journal article Identlhes the research area, explains the Importance of the research, provides background Information, cites and summarizes key literature in the held, points out what still needs to be studied, and Introduces the reader to the work presented In the article. The Methods section—formally known as Materials and Methods or Experimental (Section)— describes how the study was conducted. The Results section summarizes quantitative (and possibly qualitative) data collected during the study. In the Discussion section, authors interpret their data and suggest the larger implications and/or applications of their results. Each of these major sections can be further divided into moves, as we will see in subsequent chapters. 

Move 1 is approached slightly differently in synthesis papers (e.g., articles published in The Journal of Organic Chemistry). Such papers typically describe a series of related reactions, often totaling 10 or more individual syntheses. Rather than describe all of the chemicals used for these many reactions at the start of the Methods section, authors instead include only general information in move 1 (e.g., All NMR studies were performed on a 500 mHZ instrument. ). A common subheading for this move is General. Information about specihc reagents and materials are included in move 2, where the individual syntheses are described. 

The first move of the Methods section provides a description of chemicals, materials, and/or samples. Beginning writers often wonder what to include in this section (level of detail) and how these details should be presented (level of formality), both issues related to audience. With respect to detail, it is customary to report the name, purity, and vendor for all essential chemicals and materials used in the work. (Incidental chemicals, e.g., solvents used to clean glassware, need not be reported.) Similarly, for samples, both how and where the samples were collected should be described. With respect to formality, the journal article requires complete sentences. A common mistake is to use lists although commonplace in... 

The determination of a macromolecular crystal structure is a complicated and often laborious process, but it is often rather briefly described in the materials and methods section of a journal article. We will use the paper by Leppanen et al26 as an example of a typical crystallographic structure determination and analyze the information presented.
