"Discrimination of nuclear spin isomers exploiting the excited state dynamics of a quinodimethane derivative"

Obaid, Rana; Kinzel, Daniel; Oppel, Markus; González, Leticia (THE JOURNAL OF CHEMICAL PHYSICS 141, 164323 (2014), 2014-10-29)

Despite the concept of nuclear spin isomers (NSIs) exists since the early days of quantum mechanics, only few approaches have been suggested to separate different NSIs. Here, a method is proposed to discriminate different ...
A molecular symmetry analysis of the electronic states and transition dipole moments for molecules with two torsional degrees of freedom

Obaid, Rana; Leibscher, Monika (THE JOURNAL OF CHEMICAL PHYSICS142, 064315 (2015), 2015-02-12)

We present a molecular symmetry analysis of electronic states and transition dipole moments for molecules which undergo large amplitude intramolecular torsions. The method is based on the correlation between the point group ...
"Separating nuclear spin isomers using a pump–dump laser scheme"

Obaid, Rana; Kinzel, Daniel; Oppel, Markus; González, Leticia (Theor Chem Acc (2015) 134:46, 2015-03-29)

The concept of nuclear spin isomers was already introduced in the early days of quantum mechanics. Despite its importance, not much work has been done to separate them experimentally by pushing the ratio away from its ...
