′�?, by using a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density practical concept computations present that the residual absorption of your https://andresgeysj.jaiblogs.com/59487922/what-does-baga4se7-crystal-mean
