We investigate the role of vibrational energy excitation of methane and two deuterated species (CD4 and CH2D2) in the collision-induced dissociation (CID) process with argon at hyperthermal energies. The quasi-classical trajectory method has been applied, and the reactive Ar + CH4 system has been modeled by using a modified version of the CH4 potential energy surface of Duchovic et al. (J. Phys. Chem. 1984, 88,...
Large-scale classical trajectory calculations have been performed to study the reaction Ar + CH4 → CH3 + H + Ar in the temperature range 2500 ≤ T/K ≤ 4500. The potential energy surface used for ArCH4 is the sum of the nonbonding pairwise potentials of Hase and collaborators (J. Chem. Phys. 2001, 114, 535) that models the intermolecular interaction and the CH4 intramolecular potential of Duchovic et al. (J. Phys...
De junho/92 a maio/94, capturas de mutucas foram realizadas mensalmente em eqüino e utilizando armadilhas do tipo ?canopy?, na fazenda Nhumirim, subregião da Nhecolândia, Pantanal sul-mato-grossense. Capturas no eqüino foram realizadas do crepúsculo matutino ao vespertino, com o auxílio de redes entomológicas, em ambientes de campo e cerradão (1 dia/ambiente/mês), durante o primeiro ano do estudo. Capturas com ...
