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...

We present a study of the central zone star-forming region L1448 at 217--230 GHz ($\sim$ 1.3 mm) using ALMA observations. Our focuses on detection proto-stellar molecular outflows and interaction with surrounding medium toward sources L1448--C(N) L1448--C(S). Both exhibit continuum emission, being brightest one. Based its spectral index associated bipolar outflow, emission is most likely to be ...

The crossed molecular beam technique has been established as a mature and important experimental method for detailed studies of molecular interactions, and has contributed enormously to our present understanding of molecular reaction dynamics. The Stark deceleration technique yields unprecedented control over both the internal and external degrees of freedom of polar molecules in a molecular be...

Experiments in progress at Appalachian State University’s Ion Trap Laboratory are providing atomic and molecular data for solar, stellar, planetary, and astrophysical plasmas: collision rates coefficients, radiative decay rates of metastable ions, and unimolecular dissociation rates of ionized molecules. Processes currently under study include: collision rates of protons with H2 and He, of atom...

We report a theoretical investigation of the collision-induced dissociation pyrene dimer cation, as recently investigated in experimental work by Zamith et al. (J. Chem. Phys. 153, 054311 (2020)). Molecular dynamics simulations using potential energies and forces computed at self-consistent charge density functional-based tight binding level were conducted for different collision between 2.5 30...
