${}^{13}$C isotopic ratios of HC${}_3$N on Titan measured with ALMA

Takahiro Iino, Kotomi Taniguchi, Hideo Sagawa +1

We present the first determination of the abundance ratios of ${}^{13}$C substitutions of cyanoacetylene (HC${}_3$N), [H${}^{13}$CCCN]:[HC${}^{13}$CCN]:[HCC${}^{13}$CN] in Titan's atmosphe…
