In the FTIR, how many IR modes are predicted from the group theory according to the crystal structure ?

01 March 2023 1 2K Report

The compound is double perovskite, and belongs to monoclinic system.

Please Bilbao crystallography website (https://www.cryst.ehu.es/) give your space group and Wyckoff positions then it will calculate give the no. of IR modes and Raman modes. Of course once you know the IR mode you can find the FTIR modes also.
