This process names a type of bond discovered in 2015 between two bromines and a muonium that unusually slows down reaction rates at high temperatures. Coupling transitions between electronic energy levels and energy levels for this process require overlapping wavefunctions, per the Franck–Condon principle. The deviation from theory of the energy levels for this process is depicted on a Morse potential. In spectroscopy, (-5[1])the energy required to excite this process is usually between 1000 and 3000 (-5[1])inverse-centimeters. Nonlinear molecules with N atoms undergo this process in 3N minus 6 degrees of freedom, or normal modes. Types of this process undergone (10[1])by water molecules include scissoring, rocking, and stretching. (10[1])For 10 points, IR spectroscopy measures what type of oscillating molecular motion? ■END■ (10[2])
