DressedPathway

class DressedPathway(leaf, vib_mode, T)

Bases: rotsim2d.dressedleaf.Pathway, rotsim2d.dressedleaf.NDResonance

Excitation pathway specialized to a vibrational mode.

Parameters

• leaf (rotsim2d.pathways.KetBra) – Leaf of rotsim2d.pathways.KetBra excitation tree.

• vib_mode (molspecutils.molecule.VibrationalMode) – Object implementing molspecutils.molecule.VibrationalMode interface.

• T (float) – Temperature in Kelvin.

Attributes

base_params_dict
vib_mode	Vibrational mode associated with this pathway.
T	Temperature in Kelvin.
const	The const factor of Pathway multiplied by the fractional population of the initial state of the pathway in thermal equilibrium, molspecutils.molecule.VibrationalMode.equilibrium_pop(), and by the four-fold reduced matrix element, \(\langle \nu_i J_i\|T^{(0)}(\tilde{\mu})\|\nu_i J_i\rangle\):

Methods
