Transition Selection and Details Window

This window allows transitions of particular values of J and symmetry (for both upper and lower states) to be selected. This is especially useful for finding ground or excited state common differences (where a set of transitions either start or end with the same rotational level). To do this, select a particular J and possibly symmetry for the upper or lower state, and set the values for the other state to "all" (the lowest values on the spin boxes).Then press the button to simulate the selected transitions. To revert to the original simulation, press the button in the main window. Matrices of the transition moment operator are also displayed in this window.

Transition Select transition required.
J Select upper and lower state values of J.
Change Select the change in J (to give only P, Q or R transitions, say).
Symmetry Select symmetry for upper and lower states.
State/Manifold Allows upper and lower states to be selected (in the case of more than one transition being included in the .pgo file, for example).
Add Add lines corresponding to chosen transition to line list window.
Replace Replace lines currently in line list window with new lines corresponding to chosen transition.
Skip Leaves line list unchanged, i.e. does not add new transitions to line list.
Plot Plots selected transitions in PGOPHER's main window (instead of full spectrum).
Perturbations If cleared, excludes perturbations from the calculation.
Square Squares values in the transformed transition matrix.

Original Transition Matrix

When a transition of fixed upper and lower J, and fixed symmetry, is selected, and the transition is allowed, transition moments in the undiagonalized basis are shown in this matrix, with the ground state basis shown down the left-hand side and the upper state basis shown across the top of the matrix.  Symmetries are given in the upper left-hand corner e.g. <+||->

Transformed Transition Matrix

This contains the transition moments in the diagonalized basis.
