detection_angles

detection_angles(angles, meths=None, angles_vars=thetas)

Zeroing det. angles for a minimal complete set of pathways.

Generate a minimal complete set of non-R-factor-equivalent pathways including Q-branch transitions. The resulting dict can be used with rotsim2d.dressedleaf.equiv_peaks() or rotsim2d.dressedleaf.split_by_equiv_peaks() to identify other pathways that are also zeroed by any of the detection angles.

Parameters:

• angles (Sequence) – Light beam polarizations.

• meths (Sequence[Callable] | None) – Filters for KetBra excitation tree, see rotsim2d.pathways.gen_pathways().

Returns:

Dict from detection angles to symmetric top pathways.

Return type:
