Observation of tricarbon-hydride C3H

Crossed-beam reaction of C[3 Pj] with C2 H2 [ 1 [ g 1 ]: Observation of tricarbon-hydride C3 H

The reaction between ground state carbon atoms, C~P j), and acetylene, C2H2~ (g ), was studied at an average collision energy of ~8.460.3! kJ mol using the crossed molecular beam technique. The product angular distribution and time-of-flight spectra of m/z537, i.e., C3H, were recorded. Only m/z537 was detected, but no signal from the thermodynamically accessible C3~ (g )1H2( (g ) channel. Forwa...

Chemical dynamics of cyclopropynylidyne „ c - C 3 H ; X 2 B 2 ... formation from the reaction of C „ 1 D ... with acetylene , C 2 H

The reaction between electronically excited carbon atoms, C(D), and acetylene was studied at two average collision energies of 45 kJ mol and 109 kJ mol employing the crossed molecular beam technique. The time-of-flight spectra recorded at mass to charge m/e537~C3H ! and m/e 536(C3 ) show identical patterns indicating the existence of a carbon versus atomic hydrogen exchange pathway to form C3H ...

Investigating the chemical dynamics of the reaction of ground-state carbon atoms with acetylene and its isotopomers.

We investigated the multichannel reaction of ground-state carbon atoms with acetylene, C2H2 (X1Sigmag+), to form the linear and cyclic C3H isomers (atomic hydrogen elimination pathway) as well as tricarbon plus molecular hydrogen. The experiments were conducted under single-collision conditions at three different collision energies between 8.0 kJ mol-1 and 31.0 kJ mol-1. Our studies were comple...

Formation of resonantly stabilised free radicals via the reactions of atomic carbon, dicarbon, and tricarbon with unsaturated hydrocarbons: theory and crossed molecular beams experiments

Crossed molecular beam study on the ground state reaction of atomic boron [B((2)P(j))] with hydrogen cyanide [HCN(X(1)sigma(+))].

The linear boronisocyanide species, [BNC(X(1)Sigma(+))], represents the simplest triatomic molecule with three distinct, neighboring main group atoms of the second row of the periodic table of the elements: boron, carbon, and nitrogen. This makes boronisocyanide a crucial benchmark system to understand the chemical bonding and the electronic structure of small molecules, in particular when comp...
