′�?, which has a frequency of 295 cm−1, is attributed into the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−one phonon corresponds to your crystal IR absorption edge, as an alternative to the residual absorption peak. Density purposeful theory computations exhibit that the residual absorption in https://chanceswhcz.madmouseblog.com/12935908/the-smart-trick-of-baga4se7-crystal-that-no-one-is-discussing
