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.
[6]:
# Plot cross sections using Xarray functionality
# Set here to plot per file - should add some logic to combine files.
for data in dataXS:
daPlot = data.sel(XC='SIGMA')
daPlot.plot.line(x='Eke', col='Type')
\(\beta_{2}\) by symmetry & type¶
Types & symmetries as per cross-sections. Normalized \(\beta_{2}\) paramters, dimensionless.
[7]:
# Repeat for betas
for data in dataXS:
daPlot = data.sel(XC='BETA')
daPlot.plot.line(x='Eke', col='Type')
Dipole matrix elements¶
For 1-photon ionization. These are taken directly from ePS DumpIdy segments. See the ePS manual, ``DumpIdy` command, for further details <https://www.chem.tamu.edu/rgroup/lucchese/ePolyScat.E3.manual/DumpIdy.html>`__.

MFPADs¶
Calculated MF \(\beta\) parameters, using ePS dipole matrix elements. These are calculated by ep.mfblm(), as a function of energy and polarization geometry. See the ePSproc docs on ``ep.mfblm()` <https://epsproc.readthedocs.io/en/latest/modules/epsproc.MFBLM.html>`__ for further details, and this demo notebook.
