Can anyone tell me formula for lattice constants a, b and c in a hexagonal structure? a , b and c are units cell of structure. As we see in cubic structure we have a formula to calculate side a, b and c method known as braggs law. So what should be the method for calculating it in a hexagonal structure. I want to define the XRD (X-Ray diffraction) structure of my crystal.
