The internal rotation icon indicates there is calculated data on internal rotation or inversion corresponding to this vibrational mode. Click on the icon in the table to go to the pages on internal rotation. Other modes may correspond to internal rotation too, but we have only calculated the internal rotation potential energy surface for the indicated modes.
