In the case of the TDM, both the electric and magnetic components are plotted, if available, as the ), the LUMO (Figure ), the HOMO-LUMO pair together (Figure ), and any orbitals that are calculated to have a significant contribution to an electronic excited-state transition, by default. The 'significance' of each orbital is based on the probability of an electronic transition involving the orbital; by default, orbitals involved in transitions with > 20% probability are deemed to be significant and are included, although this value can be adjusted by the user. Any additional orbital can also be manually requested for each calculation. As an example, Figure shows a render of the HOMO-1 orbital, because the T2 excited state of pyridine has a 67% contribution from a HOMO-1 → LUMO+1 transition. The LUMO+1 orbital was also therefore rendered in this report but is not shown in Figure . Each 3D image is rendered from four different perspectives to allow the researcher to view the molecule from multiple angles, these are: 1) along the z-axis; 2) along the y-axis; 3) along the x-axis; and 4) at 45° to the three axes.
