′�?, that has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds on the crystal IR absorption edge, rather than the residual absorption peak. Density purposeful concept computations display which the residual absorption with the BGSe https://bariumnitratecrystal57901.tblogz.com/5-easy-facts-about-baga4se7-crystal-described-46501187
