✦ Synopsis

The quasïequilïbrhim vibrational distribution characterizing the intermediate relasation stage estabIished hy near-resoriant.. inter-and intra-mode coIIisionaI V-V exchanges in potyatomic moiecutes is derived through the maximum entropy pruicipIe_ When a unique set of domínant energy transfer pathways =can be identifïed one obtis famliar rehtionshïps between vibrationai mode temperatures. WIten many nearly equivatent sets are possibfe the anaIysis suggests a common vibmtional temperature. The vaIidity of the assumptions and the appIica?GIity of the resuits for explaining energy Iocalization in polyatomic molecuIes following Iaser excitation are considered. * For reviews see e.g. ref.
