High-Lying Levels of Ozone via an Algebraic Approach

摘要

An algebraic Hamiltonian for the vibrational motion in ozone, including a Darling Dennison type coupling term, is used to fit the recently observed high overtones. The good quality of the fit is due to the coupling of anharmonic normal modes by a quartic order (Darling Dennison type) coupling term. The algebraic Hamiltonian contains six parameters and these suffice to provide a better fit than the six-parameter spectroscopic term formula which uses a Darling Dennison type coupling among harmonic modes. The present results provide a hiteherto unexplored quantitative application of the algebraic approach to perturbed high lying states of triatomics. Keywords: Reprints; Ozone; and High lying levels.
