′�?, by using a frequency of 295 cm−1, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of the 295 cm−one phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful concept computations clearly show that the residual absorption from https://baga4se7crystal35789.blogprodesign.com/54263373/baga4se7-crystal-can-be-fun-for-anyone
