%% Place the body of your abstract below.
A novel method of rotational spectroscopy of trapped, cold molecular ions is presented.
It is a double resonance scheme combining rotational excitation (in the mm-wave region)
with rovibrational excitation (in the IR). The rovibrational excitation is  detected
by the recently developed leak-out spectroscopy (LOS) approach\footnote{
\href{https://doi.org/10.1021/acs.jpca.2c05767}{doi:10.1021/acs.jpca.2c05767},
P.~C. Schmid, O. Asvany, T. Salomon, S. Thorwirth, and S. Schlemmer, \textit{J. Phys. Chem. A},
\textbf{126}, 8111-8117, (2022).}$^,$\footnote{see also talk of P.~C. Schmid in Minisymposium "Spectroscopy of ions in traps"}.
LOS is based on the vibrational-translational energy transfer process occuring during the
collision of the IR excited ion with a noble gas atom, after which the ion may escape  the trap ("leak out")
so that it can be counted by a detector.
LOS and the rotational scheme based on it are very sensitive and  generally applicable to any cation or anion.
This poster presents rotational spectra for HC$_3$O$^+$, c-C$_3$H$_2$D$^+$ and H$_2$CCCH$^+$.
