′�?, by using a frequency of 295 cm−1, is attributed towards the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−one phonon corresponds to your crystal IR absorption edge, rather then the residual absorption peak. Density useful concept computations clearly show that the residual absorption with the https://baga4se7-crystal18372.get-blogging.com/33308889/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
