′�?, with a frequency of 295 cm−1, is attributed for the stretching vibration of Ga–Se bonds. The two-phonon absorption of your 295 cm−one phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density practical concept computations display that the residual absorption of your https://daltonoqtzy.activablog.com/32022537/a-simple-key-for-baga4se7-crystal-unveiled
