NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, with a frequency of 295 cm−1, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption with the 295 cm−1 phonon corresponds for the crystal IR absorption edge, rather then the residual absorption peak. Density useful principle computations present that the residual absorption from the BGSe crystal originates
