the claim

Absolute configuration is determined experimentally using anomalous X-ray dispersion or vibrational circular dichroism.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that absolute configuration is determined experimentally using anomalous X-ray dispersion or vibrational circular dichroism?

Yes. Experimental determination of absolute configuration frequently relies on techniques such as anomalous X-ray dispersion and vibrational circular dichroism.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

The retrieved literature directly supports the claim. Paper [0] explicitly utilizes anomalous scattering (X-ray dispersion) to assign absolute configuration, while papers [1] and [3] discuss vibrational circular dichroism (VCD) as established and advanced tools for absolute configuration determination. No papers contradict the claim.
