′�?, that has a frequency of 295 cm−one, is attributed to your stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−1 phonon corresponds on the crystal IR absorption edge, as opposed to the residual absorption peak. Density useful idea computations demonstrate which the residual absorption in the https://baga4se7crystal68013.tusblogos.com/32814902/the-smart-trick-of-baga4se7-crystal-that-nobody-is-discussing
