A detected feature at the expected wavelength for the HD R5(0) line in Jupiter's and Uranus' atmospheresA feature was detected at the expected wavelength for the HD R5(0) line in Jupiter's and Uranus' atmospheres. An upper limit for Neptune was also found. Added to the earlier detection of a similar feature for Saturn, it is proposed that all evidence from this type of measurement can be interpreted as arising from a D/H ratio of about .0004 for all the major planets. This value is not in agreement with measurements from CH3D transitions, and is at least fifty times the accepted interstellar medium value of 5 x .000001, implying deuterium enhancement in the solar system via fractionation in the proto-solar nebula.
