NEW STEP BY STEP MAP FOR BAGA4SE7 CRYSTAL

′�?, that has a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds into the crystal IR absorption edge, rather than the residual absorption peak. Density useful theory computations display the residual absorption from the BGSe crystal originates
