′�?, that has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−one phonon corresponds for the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical theory computations clearly show the residual absorption of https://baga4se7-crystal37147.kylieblog.com/33324998/what-does-baga4se7-crystal-mean
