Molecule Types Symmetric Tops <Prev Next>

Symmetric Top Nucleus

Note that the current implementation only handles nuclei on the top axis. Handling of off-axis equivalent nuclei is planned for a future release.

Settings

Spin Nuclear spin
AsNext Nucleus is equivalent to following nucleus

Parameters

eQq Qudrupole Coupling Constant
eQq2 Extra Qudrupole Coupling Constant for degenerate states; This is defined by analogy with eQq2 in linear molecules, and gives the same matrix elements within K = ±1 states as in Λ = ±1 states for linear molecules.
Czz Component along symmetry axis of Nuclear Spin - Rotation interaction.
Cperp Average of components perpendicular to symmetry axis of Nuclear Spin - Rotation interaction.
