Manifold

Manifolds provide a way of grouping states together. Interacting states (i.e. those with perturbations between them) must be in the same manifold, and it may be convenient to group related states together (such as a set of vibrational states from the same electronc state.) Manifolds therefore contain two types of object, states and perturbations. To add a new state or perturnation to a molecule, right-click on the manifold in the constants and select "Add new..."

The settings here are the same, whether simulating  linear, symmetric top and asymmetric top molecules.

Settings

Jmin Minimum J in calculation - set negative to take from molecule or manifold.
Jmax Maximum J in calculation - set negative to take from molecule or manifold.
Initial True to include population in this state when calculating spectra.
Colour Colour for spectra - set to "None" to get colour from elsewhere.
EigenSearch Identify state by looking for largest coefficient in eigenvector.
LimitSearch Set to assume the energy ordering within an individual state does not change, but the eigenvectors are used to select the state.
