Abstract
The ro-vibrational spectrum of HC$_3$N has been recently the object of a comprehensive study% \footnote{L. Bizzocchi, F. Tamassia, et al., {\it Astoph. J. Supp. Ser.} 233:11, 2017} which put together new high-resolution mid-infrared measurements and all existing rotational data for the vibrationally excited states located below $\sim$ 1000 \wn. The resulting global analysis yielded accurate and physically sound spectroscopic parameters for 12 states, thanks to the careful treatment of the $l$-type resonance effects in bending states and the consideration of various anharmonic resonances, in particular those connecting the polyad of states $v_4 = 1$, $v_6 = 2$, $v_5 = v_7 = 1$, and $v_7 = 4$. Here, the extension of the study to the second polyad of interacting states is presented, they are: $v_4 = v_7 = 1$, ($v_6 = 2, v_7 = 1$), ($v_5 = 1, v_7 = 2$), and $v_7 = 5$, and are located in the energy interval 1100--1300 \wn. New far- and mid-infrared spectra have been recorded at SOLEIL, with a resolution of 0.001 \wn, and further measurements of the millimeter and sub-millimeter spectra of the four interacting states have been performed at Garching and Bologna. The results of a new global analysis including all the states below $\sim$ 1300 \wn are presented and discussed.
