Abstract: The electric quadrupole fundamental (v = 1←0) band of molecular deuterium around 3 μm is accessed by cavity ring-down spectroscopy using a difference-frequency-generation source linked to the Cs-clock primary standard via an optical frequency comb synthesizer. An absolute determination of the line position and strength is reported for the first two transitions (J = 2←0 and J = 3←1) of the S branch. An accuracy of 6×10−8 is achieved for the line-center frequencies, which improves by a factor 20 previous experimental results [ A. R. W. McKellar and T. Oka, Can. J. Phys. 56, 1315 (1978) ]. The line strength values, measured with 1% accuracy, are used to retrieve the quadrupole moment matrix elements which are found in good agreement with previous theoretical calculations [ A. Birnbaum and J. D. Poll, J. Atmos. Sci. 26, 943 (1969) ; J. L. Hunt, J. D. Poll, and L. Wolniewicz, Can. J. Phys. 62, 1719 (1984) ]
