An algebraic approach applied to the determination of the polarizability in CO2
Lemus, R.; Sánchez Castellanos, M.; Carvajal Zaera, Miguel
(IOP Publishing, 2014)
A local algebraic approach to describe vibrational excitations of molecules presenting both local and normal mode behaviors is presented. This approach allows the connection with configuration space to be established. ... -
A novel connection between algebraic spectroscopic parameters and force constants in the description of vibrational excitations of linear triatomic molecules
Sánchez Castellanos, M.; Lemus, R.; Carvajal Zaera, Miguel; Pérez Bernal, Francisco (Elsevier, 2009-01)
A connection between an algebraic approach to the dynamics of triatomic molecules based on the U(2)×U(3)×U(2) Lie algebra and the traditional description in configuration space is presented. The connection is established ... -
The Potential Energy Surface of CO2 from an algebraic approach
Sánchez Castellanos, M.; Lemus, R.; Carvajal Zaera, Miguel; Pérez Bernal, Francisco (Wiley-Blackwell, 2012-05)
The potential energy surface (PES) for the ground state of the 12C 16O2 molecule is estimated through an algebraic approach based on unitary groups.It is shownthat a purely algebraic approachmay lead to a unphysical ... -
A study of the Raman spectrum of CO2 using an algebraic approach
Sánchez Castellanos, M.; Lemus, R.; Carvajal Zaera, Miguel; Pérez Bernal, Francisco; Fernández, J. M. (Elsevier, 2012-10)
The vibrational Raman spectrum of CO2 is calculated by means of the alge- braic model U(2) × U(3) × U(2). The Hamiltonian and the molecular polariz- ability tensor operators are expanded in terms of symmetry coordinates, ...
