We searched for parent volatiles in comet 103P/Hartley-2 using high-resolution infrared spectroscopic observations with NIRSPEC at Keck-2 and CRIRES at VLT-1 in late July 2010, when the comet was at heliocentric distance 1.62 AU pre-perihelion. We targeted our usual suite of parent volatiles: H2O, CH3OH, C2H6, CH4, CO, HCN, H2CO, NH3, and C2H2. This presentation will report rotational temperatures and production rates for the detected species, and upper limits for those not detected.
