Abstract
We perform vibrational spectroscopy on the $V_{0\leftarrow10}$ overtone of a trapped and sympathetically cooled CaH$^{+}$ molecular ion using a resonance enhanced two photon dissociation scheme. Our experiments are motivated by theoretical work that proposes comparing the vibrational overtones of CaH$^+$ with electronic transitions in atoms to detect possible time variation of in the mass ratio of the proton to electron $\footnote{M. Kajita and Y. Moriwaki, $J. Phys. B. At. Mol. Opt.Phys.$, $\textbf{42}$,154022(2009)}$. Due to the nonexistence of experimental data of the transition, we start the search with a broadband femtosecond Ti:Saph laser guided by theoretical calculations $\footnote{Private communication}$. Once the vibrational transition has been identified, we will move to CW lasers to perform rotationally resolved spectroscopy.
