DCO+ is one of the most common deuterated molecules in cold (TK ~ 10 K) molecular cloud cores such as TMC-1. We report the results of a survey for DCO+ and H13CO+ emission regions among a sample of low mass cloud cores. We compare the derived DCO+/HCO+ ratio (0.046±0.014) with current chemistry models for deuterium fractionation.
