Pharmaceuticals - Why 2-theta and not theta?

Expert: Michael Anisfeld - 10/11/2007

Question
Why is the X-axis in P-XRD chromatograms expressed in 2-theta instead of theta?

Answer
Rubi:

My sincere apologies, but my expertise does not extend to in-depth chemical analysis, especially in what you are asking.

My job is a GMP auditor of pharmaceutical companies, including auditing the QC Chemistry lab.
