Vibronic spectroscopy of sympathetically cooled CaH$^+$
Abstract
We report the measurement of the 1 2 transition of CaH by resonance-enhanced photodissociation of CaH that is co-trapped with laser-cooled Ca . We observe four resonances that we assign to transitions from the vibrational =0 ground state to the =1-4 excited states based on theoretical predictions. A simple theoretical model that assumes instantaneous dissociation after resonant excitation yield results in good agreement with the observed spectral features except for the unobserved =0 peak. The resolution of our experiment is limited by the mode-locked excitation laser, but this survey spectroscopy enables future rotationally resolved studies with applications in astrochemistry and precision measurement.
