| Abstract: |
We present a line survey of 10 Class 0 and 7 Class I protostars with 9 molecular lines. Combining dust continuum maps and molecular line maps, we calculated the depletion factor and deuterium enhancement to study the chemical properties. A general trend for the chemical evolution is seen: higher deuterium fractionation at higher CO depletion. |
