| They reported in the framework of improved data of the above survey the detection of the three HNC<sub>3</sub> <sup>13</sup>C isotopomers. They determined the <sup>12</sup>C/<sup>13</sup>C ratios of ~90 with scatter that is insignificant with respect to the uncertainties. These values are somewhat lower than ~65 usually found in the the local ISM, but very similar to values of HCCNC <sup>13</sup>C isotopomers and to two of the three HC<sub>3</sub>N <sup>13</sup>C isotopomers. In addition, an H/D ratio of ~53 was reported, similar to the value of 57 ± 2 of HC<sub>3</sub>N.\\ |
