Reaction Dynamics of NH2+OH on an Interpolated Potential Energy Surface

QCT calculations were performed to study the behavior of energized NH2OH formed by association collision of NH2 radical with OH radical. A potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. H2O, HON, HNO, NH3, O, H2NO, cis or trans-HONH, and H products and two vibrationally energized NH2OH and NH3O adducts were obs...

Interpolated potential energy surfaces and dynamics for atom exchange between H and H3(+), and D and H3(+).

Two ab initio interpolated potential energy surfaces have been constructed to study the dynamics of atomic hydrogen/deuterium exchange in collisions of H(3)(+) with H (D). One of the surfaces is based on energy calculations using quadratic configuration interaction with single and double excitations. The second includes a perturbative treatment of the triple excitations and an additive correcti...

State-selective predissociation dynamics of methylamines: the vibronic and HD effects on the conical intersection dynamics.

The photodissociation dynamics of methylamines (CH(3)NH(2) and CD(3)ND(2)) on the first electronically excited state has been investigated using the velocity map ion imaging technique probing the H or D fragment. Two distinct velocity components are found in the H(D) translational energy distribution, implying the existence of two different reaction pathways for the bond dissociation. The high ...

Influence of rotation and isotope effects on the dynamics of the N((2)D)+H(2) reactive system and of its deuterated variants.

Integral cross sections and thermal rate constants have been calculated for the N((2)D)+H(2) reaction and its isotopic variants N((2)D)+D(2) and the two-channel N((2)D)+HD by means of quasiclassical trajectory and statistical quantum-mechanical model methods on the latest ab initio potential-energy surface [T.-S. Ho et al., J. Chem. Phys. 119, 3063 (2003)]. The effect of rotational excitation o...

Unusual Thresholds and Isotope Effects in Al+ + H2/D2/HD Reactions

Ab initio quantum chemistry is used to generate a three-dimensional reactive potential-energy surface for the collision of 1S Al+ ions with ∑g H2 molecules. This surface, in a tessellated and locally interpolated form, is used to generate forces for classical trajectory simulations of the 3.98 eV endothermic Al+ + H2 f AlH+ + H reactions with initial conditions appropriate to a thermal H2 sampl...
