The electronic structure of biradicals is characterized by the presence of two unpaired
electrons in degenerate or near‐degenerate molecular orbitals. In particular, some of the …

α-Alkynyldiazomethanes, generated in situ from the corresponding sulfonyl hydrazones in
the presence of a base, can serve as effective metalloradicophiles in Co (II)-based …

We present the photoelectron spectra of C3Hx (x= 0–3) formed in a microwave discharge
flow-tube reactor by consecutive H abstractions from C3H4 (C3Hx+ F→ C3Hx− 1+ HF (x= 1 …

In this paper, the results of a comprehensive theoretical investigation of neutral HCnH0 and
charged HCnH±chains are reported using state‐of‐the‐art compound model chemistries …

Mass-selective threshold photoelectron spectroscopy in the gas phase was employed to
characterize the dialkynyl triplet carbenes pentadiynylidene (HC5H) …

The propargyl radical is considered to be of key importance in the formation of the first
aromatic ring in combustion processes. Here we study the bimolecular (self-) reactions of …

Most existing studies assign a polyynic and cumulenic character of chemical bonding in
carbon-based chains relying on values of the bond lengths. Building on our recent work, in …

We use gas-phase negative ion photoelectron spectroscopy to study the quasilinear
carbene propargylene, HCCCH, and its isotopologue DCCCD. Photodetachment from …

We report a joint theoretical and experimental study on the photodissociation of the C3H2
isomer propargylene, HCCCH, combining velocity map imaging with nonadiabatic trajectory …

We investigate the photoionization of the alkyl radicals 2-propyl (C 3 H 7), termed also
isopropyl, and t-butyl (C 4 H 9). Both species were generated by flash pyrolysis from suitable …
