The Study of Dynamic Potentials of Highly Excited Vibrational States of DCP: From Case Analysis to Comparative Study with HCP
نویسندگان
چکیده
The dynamic potentials of highly excited vibrational states of deuterated phosphaethyne (DCP) in the D-C and C-P stretching coordinates with anharmonicity and Fermi coupling are studied in this article and the results show that the D-C-P bending vibration mode has weak effects on D-C and C-P stretching modes under different Polyad numbers (P number). Furthermore, the dynamic potentials and the corresponding phase space trajectories of DCP are given, as an example, in the case of P = 30. In the end, a comparative study between deuterated phosphaethyne (DCP) and phosphaethyne (HCP) with dynamic potential is done, and it is elucidated that the uncoupled mode makes the original horizontal reversed symmetry breaking between the dynamic potential of HCP ( q 3 ) and DCP ( q 1 ), but has little effect on the vertical reversed symmetry, between the dynamic potential of HCP ( q 2 ) and DCP ( q 3 ).

Dynamic Features of the Highly Excited Vibrational States of the HOCl Non-Integrable System Based on the Dynamic Potential and Lyapunov Exponent Approaches.
In this article the dynamic features of the highly excited vibrational states of the hypochlorous acid (HOCl) non-integrable system are studied using the dynamic potential and Lyapunov exponent approaches. On the condition that the 3:1 resonance between the H-O stretching and H-O-Cl bending modes accompany the 2:1 Fermi resonance between the O-Cl stretching and H-O-Cl bending modes, it is found...
متن کاملObservation of the “isomerization” States of Hcp: “isomerization” State vs. “normal- Mode-type” State
Among various kinds of bond-breaking isomerization reactions, the isomerization of a triatomic monohydride, HAB, is the simplest one: HAB ABH. This system is most fundamental for both experimental and theoretical studies. On the basis of a time-independent picture, the isomerization process can be characterized by analysis of rotation-vibration eigenstates in the high energy region. In this stu...

Food security has a dynamic notion during the time and may be affected by various domestic and global factors.Nevertheless, Iranian policy makers consider food security as same as self-sufficiency in agricultural food products, particularly wheat production. However, self-sufficiency can contribute to food security only if it is in coincidences with comparative advantage and sustainable resourc...
متن کاملHighly excited vibrational states of HCP and their analysis in terms of periodic orbits: The genesis of saddle-node states and their spectroscopic signature
We present quantum mechanical bound-state calculations for HCP(X̃) using an ab initio potential energy surface. The wave functions of the first 700 states, corresponding to energies roughly 23 000 cm above the ground vibrational state, are visually inspected and it is found that the majority can be uniquely assigned by three quantum numbers. The energy spectrum is governed, from the lowest excit...
