This new proposal extends and completes our previous project ABAUDRY.PROP_OD1 with the inclusion of new deuterated molecular sources which were recently discovered with the IRAM-30m telescope. In these sources we wish to detect and analyze the same three IR lines of OD as in ABAUDRY.PROP_OD1. We add this new sample to investigate a broader variety of OD sources including the most important target Orion. The OD radical, although predicted to be abundant by various chemical scenarios, has never been observed in space but will give important clues to D fractionation. The selected OD lines correspond to energy levels comparable to or lower than those involved in detected HDO and OH lines. From this, and because of the relatively high temperatures of the hot cores we infer that OD will be excited and will allow us to estimate its abundance relative to OH.
