title: Absolute Raman frequency measurement of the Q(2) line in D(2) using cw CARS.
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 D(2). The preliminary value found is 2987.237(1) +/- 0.001 cm(-1). Such precision is essential for the testing of ab initio energy-level calculations for the hydrogen isotopes.
