Open-shell molecules such as radicals, carbenes, and electronically excited-state molecules
exhibit high energies, and thus, in general, they are quite reactive. 1 The short-lived species …

Negative ion photoelectron spectroscopy (NIPES) coupled with electrospray ionisation (ESI)
has been proven to be a powerful gas-phase spectroscopic tool for characterising electronic …

Ion specificity, a widely observed macroscopic phenomenon in condensed phases and at
interfaces, is a fundamental chemical physics issue. Herein we report our recent studies of …

Oxocarbons (C n O n, n= 3, 4, 5, 6,…) are a series of compounds that are only composed of
carbonyl groups. The highly electrophilic carbon atoms in C n O n make their poor stability …

Annulated rosarins, β, β′-bridged hexaphyrin (1.0. 1.0. 1.0) derivatives 1–3, are formally 24
π-electron antiaromatic species. At low temperature, rosarins 2 and 3 are readily …

Electron beam processing of surface-grown coordination polymers is a versatile approach to
the fabrication of nanoscale surface structures. Depending on their molecular components …

Cyclobutane-1, 2, 3, 4-tetrone has been both predicted and found to have a triplet ground
state, in which a b2g σ MO and an a2u π MO are each singly occupied. The nearly identical …

The carbon suboxide anion with an asymmetric zigzag structure, C3O2–, which was recently
characterized in a solid neon matrix, has not been observed in the gas phase. Here, we …

Cyclobutane-1, 2, 3, 4-tetraone has been both predicted and found to have a triplet ground
state, in which a b2g σ molecular orbital (MO) and an a2u π MO are each singly occupied. In …

Negative ion photoelectron (NIPE) spectra of the radical anion of cyclopropane-1, 2, 3-
trione,(CO) 3•–, have been obtained at 20 K, using both 355 and 266 nm lasers for electron …
