The ChiralIR–2X VCD measures the differences in absorbance between left and right circularly polarized IR radiation. VCD is an analytical method for determining the absolute configuration of chiral molecules, extending the functionality of electronic circular dichroism into the IR spectral region. 

The combination of the stereo-sensitivity of circular dichroism with the structural specificity of FT-IR spectroscopy, provides access to multiple well-defined bands that provide quantitative information about the sample.
