Scientists have achieved the first real-time visualization of how 'excited-state aromaticity' emerges within just hundreds of femtoseconds and then triggers a molecule to change from bent to ...

Due to the inherent low atomic number of organic materials, their ability to absorb high-energy rays is relatively weak.

So, when an atom in a crystal lattice array is prepared in the excited state, it relaxes back to the ground state after some ...

Rare cases exist of divalent carbon compounds called carbones, where a central neutral atom in an electronically excited state is stabilized by two bonds with neutral electron-pair donating groups.
