The dynamics of the carbonium ion (CH5 +), a highly reactive intermediate with no equilibrium structure, was studied by measuring the infrared spectra for internally cold CH5 + (H2) n (n = 1, 2, 3) stored in an ion trap.

At the other end of the spectrum are superconducting circuits — pursued for instance by IBM and Google — and ion traps.

This effect is also exploited by the team to heat the rotational motion of the molecular ions through the amplification of the regular micro-motion of trapped particles.
