′�?, that has a frequency of 295 cm−one, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds on the crystal IR absorption edge, in lieu of the residual absorption peak. Density useful concept computations display which the residual absorption from the https://franciscojaehh.blogocial.com/everything-about-baga4se7-crystal-68473397
