This word follows the prefix "centro" to describe point groups with this property about an inversion center.
This property inversely correlates with the intensity of the pre-edge transition region in k-edge spectroscopy. In molecules with this property, normal modes cannot be both infrared and Raman active, according to the rule of mutual exclusion. In molecules with this property, only transitions from ungerade ("oon-geh-RAH-duh") to gerade ("geh-RAH-duh"), or vice versa, are permitted by the Laporte rule. Rows of ones and negative ones make up character tables, which provide information about the operations named for this property. This word follows the prefix "centro" to describe point groups with this property about an inversion center. Polar molecules must lack this property so that their bond dipoles don't cancel each other out. For 10 points, name this property that ensures that molecules will remain the same after a rotation or internal reflection.
This property inversely correlates with the intensity of the pre-edge transition region in k-edge spectroscopy.
