Reassigning the CaH${}^{+}$ 1${}^1\Sigma \to$ 2${}^1\Sigma$ vibronic transition with CaD${}^{+}$

John Condoluci, Smitha Janardan, Aaron T. Calvin +3

We observe vibronic transitions in CaD${}^{+}$ between the 1${}^1\Sigma$ and 2${}^1\Sigma$ electronic states by resonance enhanced multiphoton photodissociation spectroscopy in a Coulomb crystal…
