dc.description.abstractIn the framework of the investigation of the relaxation mechanisms of molecular rotational and vibrational excitations in a superfluid helium cluster environment, the first microwave absorption spectra have been obtained for He clusters doped with acetonitrile $(CH_{3}CN)$. Two broad $(\approx 1 GHz)$ peaks centered at about 12.5 and 15 GHz have been observed using bolometric detection of the beam attenuation caused by successive absorption of several microwave photons in a 10 cm long waveguide. The change in rotational constants induced by the presence of the medium preclude assignment based on a mere comparison with gas phase spectra. Further measurements are currently in progress to assign the observed features and determine the rotational relaxation times of the system.en_US
