HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD BAGA4SE7 CRYSTAL

′�?, which has a frequency of 295 cm−1, is attributed to the stretching vibration of Ga–Se bonds. The 2-phonon absorption from the 295 cm−one phonon corresponds on the crystal IR absorption edge, as an alternative to the residual absorption peak. Density functional principle computations demonstrate which the residual absorption with the
