Most forms of chemical representation were developed with these uses in mind. A convenient mnemonic for these tasks is “RSVP”: Register, Search, View, Publish. In this module, we’ll focus on the communications tasks that almost all chemists engage in. Later modules of this course will focus on how these various sorts of identifiers are used in cheminformatics applications. In Part 2, we’ll introduce several chemical identifiers and representations developed specifically for use on computers. In Part 1 of this module, we will dig into the most common kinds of chemical names, formulas, and notation to figure out a) how they work, b) why they work like they do, c) where they are most often used, and d) what they do and do not tell you about a chemical structure. You can minimize the impact of this kind of miscommunication by keeping in mind what various sorts of chemical names and formulas DO and DO NOT tell you about a particular compound, and by documenting the sources of the names and formulas that you use. When it is detected, it’s often difficult to figure out what went wrong. In these cases, it’s often easier for miscommunication to go undetected. Often, it also involves different computer systems communicating with each other. However, work in cheminformatics almost always involves communicating not just with other chemists, but with computer systems. Experienced human chemists are generally able to figure out when they’ve misunderstood each other over the identity of a particular compound. Where there’s communication, there’s always a danger of misunderstanding. In this module, we’re going to turn things around and think about chemical names, formulas, and notation themselves. You’re probably already so accustomed to chemical names, formulas, and notation that you barely need to think about them when you use them, and can instead focus on the molecules that you’re drawing, writing, or talking about. You do so using chemical names, formulas, and notation. In the classroom, in the laboratory, or at the computer screen, as a chemist, you are constantly referring to all sorts of different chemical substances and molecular entities. Communicating chemical structure with formulas and namesĬhemistry involves a lot of communication.
