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 ...

When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin ...

Aromatic molecules consist of planar carbon-based rings with alternating single and double (π) bonds. These molecules contain 4n+2 (n = 0, 1, 2 ...) π electrons—π electrons are those involved in π bonds—which results ...
