โฆ Synopsis
ChanSes of the rotaticnal quantum state occurring simultancousi~ (in one arr~k collision step) Edith the deactivation of _ the torsional vibration ~7 ha%e been measured in $1 OUI IA,. Selscthe ewirarron of rotational Ie\eIs in the vibronic MeI 7' 85s accomplished by means of ;I tunable d> e laser. X near thermal distribution of rotational le\eis in the 0' srznt was attnined as the result of 3 sing,le collision_ Intramolecular \lbration-to-rotation transfer wx not found. Smrilarl~, a ne;lrl! thermalized distribution of rotational levels in the 0' state has been ob>ened as the result of one smgle collision after selectne e_\citation of rt restricted number of rotational iereIs in the \ibronic 8' state in the presence of difiercnt collision partners

A representation of the effective rotational Hamiltonian in the form of optimum versions of a rational series of the perturbation theory is suggested for nonisolated molecular states. This representation is used to analyze the most complete set of precise transition frequencies in the rotational spe
