′�?, which has a frequency of 295 cm−one, is attributed to the stretching vibration of Ga–Se bonds. The two-phonon absorption on the 295 cm−1 phonon corresponds to your crystal IR absorption edge, in lieu of the residual absorption peak. Density useful theory computations show which the residual absorption on the https://baga4se7crystal97005.targetblogs.com/32968266/5-tips-about-baga4se7-crystal-you-can-use-today
