Transition Selection and Details Window

This window allows transitions with selected state, quantum numbers and rovibronic (rotational × vibrational × electronic) symmetry to be displayed. 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 rovibronic symmetry or eigenvalue number for the upper or lower state, and set the values for the other state to "all" (clear the box, or use the lowest value on the spin boxes). Then press the Simulate button (if necessary) to simulate the selected transitions. To revert to the original simulation, press the Simulate button in the main window. Matrices of the transition moment operator are also displayed in this window if the selection is restricted to a single upper and lower state J and symmetry. If External Fields are present, the "J" is replaced by M and the symmetry is ignored.

Check to display S or S½ rather than Spol or Spol½. See Transition Matrix Elements and Line Strengths for a discussion of this.
OrgGrid When a transition of a particular upper and lower J, and 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.
