사라진 빛의 섬광이 분자의 비밀을 드러냈다

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once thought impossible for fluids. When they mixed nearly identical chemicals, one combination behaved strangely—producing less light and erasing a single harmonic signal altogether. Simulations revealed that a subtle molecular “handshake” was interfering with electron motion. The discovery shows that liquids can briefly organize in ways that dramatically change how electrons behave.
