′�?, with a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The 2-phonon absorption of your 295 cm−1 phonon corresponds to the crystal IR absorption edge, as opposed to the residual absorption peak. Density functional principle computations clearly show which the residual absorption on the https://elliottrvuqn.blogchaat.com/32516062/a-secret-weapon-for-baga4se7-crystal
