Just over a year ago, researchers reported that they had isolated and characterized a long-sought second form of acetylsalicylic acid, known in most households as aspirin (J. Am. Chem. Soc. 2005, 127, ...

Aspirin is not only an important drug, but also an interesting physics model system in which molecular vibrations and electrons are coupled in a particular way. For the first time, X-ray experiments ...

When you get a headache, you probably reach for aspirin. What is giving researchers a headache is the question of the crystal structure of aspirin. Is there another form on top of the long-known one?

(a) Aspirin pills. (b) Crystal structure of aspirin representing a regular, spatially periodic arrangement of molecules. (c) The animation illustrates the redistribution of electron density during the ...

"The two crystalline forms of aspirin are so closely related," explain Andrew D. Bond, Roland Boese and Gautam R. Desiraju in Angewandte Chemie, "that they form structures containing domains of both ...
