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 planar ...

Single-wall carbon nanotubes are cylindrical graphite ... photoluminescence and electroluminescence from the lowest excited state is observed, adhering to Kasha's rule and indicating the potential ...

Rare cases exist of divalent carbon compounds called carbones, where a central neutral atom in an electronically excited ...
