 **How to find and apply information for required standards in chemotion repository**<br />
 The <i>page general topics</i> describes the overall idea of how to deal with data in chemotion repository. This page does not contain details on how to deal with analytical data or how to describe certain types of data. This detailed information can be found at the page "details and standards for analyses" and subpages belonging to it. It does not give information on the data files and types that are supported or need to be provided - this information is part of the section "details and standards for data types" in this documentation.

 **What kind of data should be or can be provided**<br />
 The Chemotion repository was established to store comprehensive information wherever available. If chemical reactions were done, please provide the information on the reaction and the target compounds (including their characterization). Only if the process description is not available or not relevant (e.g. for commercial compounds) sample only data should be submitted. In general, the repository should be used to provide information on scientific processes and their outcome with the full description of both.

 If a required type of data is not obtainable, the reason for the absence of the data should be noted. For example, if the compound is little soluble and recording a 13C NMR spectrum is not possible or if the compound can be hardly ionized and mass spec cannot be gained, please add a note to "Additional information for publication and purification details". For cases where the data was gained but does not meet the requirements, please see the information in the section <i>analyses</i> of this documentation. <br />
 
 ## Numbers and units
+### General formating
 - Please use numerals with units of time or measuread. Use space between numbers and units according to common standards: All combinations of number and unit should be given with space. Examples: 12 h, 12 min, 12 °C, 12 mM. <br />
 Exceptions: number+% (e.g. yield or concentration), and $, ° (angular degrees), ′ (angular minutes), and ″ (angular seconds). <br />
 Examples: the product was obtained in 12% yield or 5% methanol in water. Others: $250, 47°8′23″, 180° (but 180 °C) <br />
