We present a superfluid hydrodynamic model for the increase in moment of inertia, $\Delta I$, of molecules rotating in liquid $^4$He. The static inhomogeneous He density around each molecule (calculated using the Orsay-Paris liquid $^4$He density fun

Single and Double Resonance Microwave Spectroscopy in Superfluid $^4$He Clusters

Autor: Reinhard, I., Callegari, C., Conjusteau, A., Lehmann, K. K., Scoles, G.

Publikováno v: Phys.Rev.Lett. 82, 5036 (1999)

Purely rotational transitions of a molecule, such as HCCCN, embedded in large $^4$He clusters have been detected for the first time. The saturation behavior shows that, in contrast to previous expectations, the microwave line profiles are dominated b

We use double-resonance spectroscopy with cavity-enhanced comb probe to measure sub-Doppler transitions in the 3ν3←ν3 band of CH4. We assign the final states using different pump/probe combinations reaching the same state, and the dependence of l
