This is not a list of the top 100 chemists on Twitter. For a start, I’m not really comfortable defining ‘top’. Most followers? Most tweets? Shiniest avatar? Funniest bio? Most well-known in the real world? (Define ‘well-known’ and ‘real world’, go on, I dare you). Secondly, not everyone on this list is necessarily a card-carrying chemist, but they are all people who, more often than not, have something to say on Twitter about chemistry in all its many guises.

This is essentially a starter pack for those interested in hearing about some chemistry on Twitter (and was, perhaps obviously, inspired by the list that Science put out last week that didn’t have any chemists on it, amongst other problems…). I started writing down names and kept going until I got to 100. As with any list, its content is biased by the person who created it (me, so in this case you’ll find lots of journalists, editors and others that I regularly interact with on Twitter) and is woefully incomplete. I have no doubt that there are significant omissions; but 100 is a nice round number and so I stopped there (I also have a day job). Feel free to leave comments, including the names of your favourite chemtweeps that I have inevitably missed, and to criticize, analyze and deconstruct this list to your heart’s content. Also let me know if any links are wrong/broken.

There were some parameters though. I haven’t chosen any organizations, publications or research groups – I’ve tried to limit it to individuals. However, if you want to get lots of chemistry on Twitter, I do highly recommend @cenmag, @ChemistryWorld, @RealTimeChem, @periodicvideos and @NatureChemistry (FYI, I’m the editor of that last one, so might be a teeny bit biased). I also haven’t included any of the chemists who currently work on the journal, so apologies to @stephengdavey, @HansellThe, @RussJKJohnson, @NChemGav and @anneintokyo.

The list below is in alphabetical order of Twitter @names (well played @_byronmiller) and can be found as a list on Twitter here.
