Vibrational ground state properties of H(5)(+) and its isotopomers from diffusion Monte Carlo calculations.

The Journal of chemical physics

Acioli PH, Xie Z, Braams BJ, Bowman JM.
PMID: 18345899
J Chem Phys. 2008 Mar 14;128(10):104318. doi: 10.1063/1.2838847.

Diffusion Monte Carlo computations, with and without importance sampling, of the zero-point properties of H(5)(+) and its isotopomers using a recent high accuracy global potential energy surface are presented. The global minimum of the potential possesses C(2v) symmetry, but...

Zero-point energy constraint in quasi-classical trajectory calculations.

The journal of physical chemistry. A

Xie Z, Bowman JM.
PMID: 16623473
J Phys Chem A. 2006 Apr 27;110(16):5446-9. doi: 10.1021/jp055861e.

A method to constrain the zero-point energy in quasi-classical trajectory calculations is proposed and applied to the Henon-Heiles system. The main idea of this method is to smoothly eliminate the coupling terms in the Hamiltonian as the energy of...

Deuteration effects on the structure and infrared spectrum of CH5(+).

Journal of the American Chemical Society

The CH5+ molecular ion is well-known for its large amplitude motions that lead to complete scrambling of the hydrogen atoms, even in the vibrational ground state. Experiments have been reported that probe the consequences of these large amplitude motions....

Alterations in skeletal and mineral metabolism following thermal injuries.

Journal of musculoskeletal & neuronal interactions

Shea JE, Bowman BM, Miller SC.
