Summary Pnictinidenes (RE, where E= P, As, Sb, or Bi) are long-sought-after reactive
species. They feature either a singlet or triplet ground state depending on the electronic …

Mass spectrometry (MS) has become the central technique that is extensively used for the
analysis of molecular structures of unknown compounds in the gas phase. It manipulates the …

Under an atmosphere of carbon monoxide (CO), a (phosphino) diazomethyl anion salt [[P]‐
CN2][K (18‐C‐6)(THF)](1)([P]=[(CH2)(NDipp)] 2P; 18‐C‐6= 18‐crown‐6; Dipp= 2, 6 …

Isolation of triplet pnictinidenes, which bear two unpaired electrons at the pnictogen centers,
has long been a great challenge due to their intrinsic high reactivity. Herein, we report the …

Abstract Carbyne anions (R–C–) are one of the least explored and most poorly understood
subvalent carbon species and, so far, have only been observed in the gas phase. In this …

The rich chemistry of transition-metal (TM) carbyne complexes has fueled their application in
a wide range of fields, from synthetic chemistry to materials science. The isomeric forms of …

A portable reagent inlet system for a linear quadrupole ion trap (LQIT) mass spectrometer
was designed to diminish the impact of air and water on gas-phase ion–molecule reactions …

To compare the ion–molecule reaction mechanism of CHCl radical dot− with HCHO and H 2
O, the DFT-BHandHLYP level of theory with the aug-cc-pVDZ basis set was used. Our …

Context In this discussion, we began building two model, S2O+ CHCl•− and O3+ CHCl•−,
using DFT-BHandHLYP method, to study their reactions mechanisms on singlet PES. For …
