Ultraprecise Molecular Spectroscopy of HD+ ions

Caption

HD+ molecular ions (yellow and red pairs of dots: proton and deuteron; the electron is not shown) suspended in an ultra-high vacuum between atomic ions (blue dots), which are immobilised using a laser beam (blue). An electromagnetic wave (red-brown discs) causes the molecular ions to rotate. A further laser beam (green) records evidence of this excitation. The drawing is not to scale.
