Abstract

Coherent anti-Stokes Raman spectroscopy (CARS) is combined with high-resolution interferometry to measure the absolute Raman shift of the Q(2) vibrational line in D₂. The preliminary value found is 2987.237₁ ± 0.001 cm⁻¹. Such precision is essential for the testing of ab initio energy-level calculations for the hydrogen isotopes.
