|Objects Mixture Species Molecule Transition Moments||<Prev Next>|
A Transition Moments object will have one or more transition moment objects underneath it, which control the strength of calculated transitions and level shifts in external fields. See see Linear Molecule, Symmetric Top, Asymmetric Top or Vibrating Molecule for the possible types. Though there are no properties formally common to all, each will have some form of strength parameter that will reflect the size of the electric or magnetic dipole or other relevant property.
Note that versions of PGOPHER before 7.1.315 had a C
and D parameter to allow some modelling of J
dependence of the transition moment. This functionality has been
replaced by the more general Custom Transition Moment
Function. Data files containing non-zero C or D
values are converted to use this automatically on loading.
