N2 - A method is presented to measure the decay rate of the first excited vibrational state of polar molecular ions being part of a Coulomb crystal in a cryogenic linear Paul trap. Specifically, we have monitored the decay of the v=1,J=1>X towards the v=0,J=0>X level in MgH+ by saturated laser excitation of the v=0,J=2>X - v=1,J=1>X transition followed by state selective resonance-enhanced two-photon dissociation out of the v=0,J=2>X level. The technique can be extended to other simple molecular ions and it enables the determination, with an accuracy at the few percent level, of decay rates and thus absorption strengths.
