′�?, that has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption from the 295 cm−1 phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical concept computations display which the residual absorption with https://baga4se7-crystal62850.blogsvirals.com/31993631/a-simple-key-for-baga4se7-crystal-unveiled
