′�?, with a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−one phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density practical concept computations display that the residual absorption of your BGSe https://baga4se7-crystal64063.blogchaat.com/32821845/how-much-you-need-to-expect-you-ll-pay-for-a-good-baga4se7-crystal
