CN(N = 1→0, J = 3/2→1/2) has been searched for toward 8 locations in the Taurus dark cloud complex where NH3 and HC3N and/or HC5N have been observed. CN was detected in TMC1(NH3) and TMC2(cont.) and was probably detected in L1533(NH3) and L1544(NH3). CN appears to be correlated with NH3 and anti-correlated with HC5N and HC3N. It is postulated that NH3 is likely a dominant precursor of CN and HCN but that CN and HCN are probably not important precursors of HC3N and heavier cyanopolyacetylenes.
