′�?, which has a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−1 phonon corresponds for the crystal IR absorption edge, as opposed to the residual absorption peak. Density purposeful concept computations show that the residual absorption on the https://baga4se7crystal79023.livebloggs.com/39069786/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
