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

Photoluminescent materials are more than just the glow-in-the-dark stars your parents glued to your bedroom ceiling as a ...

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

and suggests new techniques for the observation of these excited states.

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 ...

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.
