The product rotational polarization in the Ca + HCl→CaCl + H reaction at collision energy of 20 kcal/mol has been studied via the quasiclassical trajectory method on a new ab initio potential surface. The P(θ r ) distribution of angle between k and j′, and the dihedral angular distribution P(Φ r ) characterizing k - k′ - j′ correlation are discussed, the angle distribution P(θ r , Φ r ) of product rotational vectors in the form of polar plot in θ r and Φ r are shown. Furthermore, four PDDCSs (2π/σ)(dσ00/dωt), (2π/σ)(dσ20/dωt), (2π/σ)(dσ22+/dωt) and (2π/σ)(dσ21-/dωt) are also presented. The present calculations reveal that the product rotational alignment is very strong. Finally, the state distributions of the product CaCl are investigated. The results showed that the CaCl product was formed with high vibrational and rotational excitation.

A Direct Method

The transformation method that was originally used to tailor the physical fields into desired spatial patterns by designing material parameters is used herein to obtain necessary local dynamic parameters when the state distribution of a network system is prescribed in space. This constitutes a typical inverse problem that controls the state distribution of a complex network by designing its local dynamic parameters. Thus, it is difficult to obtain a direct solution. This coordinate transformation provides a direct method. The feasibility of this method is demonstrated and verified by two examples (a communication field bender and a communication field cloak) in corresponding network systems.

The photodissociation of methyl nitrite CH3ONO in three different electronically excited states has been studied by determining the internal state distribution of one of the photofragments. The fluorescence of NO A Σ2+ produced for excitation of CH3ONO between 1200 and 1650 Å and of CH3O 2 A1 produced at 1930 Å has been investigated. The vibrational distribution in both species can be explained by statistical considerations. The rotational excitation of NO A Σ2+ is of Boltzmann type. For CH3ONO excited in the first nπ* excited state at 3550 Å the NO X fragment has been probed by a two photon laser excited fluorescence technique. The nascent NO X υ″ = 0, 1, 2, 3 exhibit a population inversion and a high degree of rotational excitation.
