It's hard to see certain molecules react. The reaction is just that fast. Until now. A team of scientists devised a way to reveal time- and energy-resolved information on "dark" states of molecules—ones that are normally inaccessible. Their approach? They control the evolution of a highly electronically excited molecule by nonlinear optical methods in the extreme ultraviolet spectrum.
