′�?, which has a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of the 295 cm−one phonon corresponds into the crystal IR absorption edge, in lieu of the residual absorption peak. Density practical concept computations display which the residual absorption with the https://kylerbghhf.blogpostie.com/54427391/baga4se7-crystal-options
