Core-Level Spectroscopy Decodes Bond-Alternation Dynamics of Cyclo[18]Carbon
The advent of X-ray free-electron lasers and high-harmonic generation has made time-resolved X-ray spectroscopy a powerful tool for probing local atomic environments, yet whether localized core excitations can report on global collective distortions remains open. Cyclo[18]carbon (C$_{18}$), with its polyynic ground sta...
