1-photon ePS Cross-Sections

Plot 1-photon cross-sections and \(beta_2\) parameters (for an unaligned ensemble) from ePS calculations. These are taken directly from the ePS output file, CrossSection segments. See the ePS manual, ``GetCro` command, for further details <https://www.chem.tamu.edu/rgroup/lucchese/ePolyScat.E3.manual/GetCro.html>`__.

Cross-sections by symmetry & type

Types correspond to:

  • ‘L’: length gauge results.

  • ‘V’: velocity gauge results.

  • ‘M’: mixed gauge results.

Symmetries correspond to allowed ionizing transitions for the molecular point group (IRs typically corresponding to (x,y,z) polarization geometries), see the ePS manual for a list of symmetries. Symmetry All corresponds to the sum over all allowed sets of symmetries.

Cross-section units are MBarn.
