Addressing and manipulation of individual hyperfine states in cold trapped molecular ions and application to HD^{+} frequency metrology
U. Bressel, A. Borodin, J. Shen +3
Advanced techniques for manipulation of internal states, standard in atomic physics, are demonstrated for a charged molecular species for the first time. We address individual hype…

Observation of a rotational transition in trapped and sympathetically cooled molecular ions
J. Shen, A. Borodin, M. Hansen +1
We demonstrate rotational excitation of molecular ions that are sympathetically cooled by laser-cooled atomic ions to a temperature as low as ca. 10 mK. The molecular hydrogen ions…
