Description
Kim Greis and co-authors read the infrared fingerprints of fluorenyl cations held in ultracold helium drops, in a study from two thousand twenty-three. The ions are classic cases in the old puzzle of ring systems that break the aroma rule. Bare ions were made by spray, sorted by mass, then trapped in cold drops.
A tunable laser scanned a wide infrared band at fine detail. Matched with density functional math, the sharp spectra show all ions sit in their singlet state. The result pins shapes for a textbook antiaromatic family in the gas phase. Readers in physical chemistry get clean spectra where warmth and solvent blur are gone.
