This molecule puts a new twist on the Möbius strip

It’s half as twisty as the paper loops common in math classes

A ring of 13 gray spheres sandwiched by two green spheres, with red and blue regions spiraling around it.

A half-Möbius molecule is made of carbon atoms (gray) and chlorine (green). Red and blue regions show the twisty wave function for electrons added to the molecule. A wave function is a quantum concept that is related to the probability of finding an electron in a given location.
