Summary

We present a model for the accumulation of energy in molecules through energy migration followed by up-conversion. We account for thenonrandom distribution of excited molecules, a consequence of the fact that nonresonant energy up-conversion occurs preferentially at closely spaced molecular sites. The model describes well the vibrational-energy accumulation of CO molecules embedded in argon.

Riassunto

Si presenta un modello per l’accumulazione di energia nelle molecole attraverso la migrazione di energia seguita per sovraconversione. Si spiega la distribuzionenon casuale delle molecole eccitate, una conseguenza del fatto che la sovraconversione di energia non risonante avviene preferenzialmente in siti molecolari a spaziatura stretta. Il modello descrive bene l’accumulazione di energia vibrazionale delle molecole di CO incluse in gas argon.

Резюме

Мы предлагаем модель накопления энергии в молекулах в результате миграции энергии с последующим возрастанием энергии. Мы обьясняем неупорядоченное распределение возбужденных молекул следствием того факта, что нерезонансное возрастание энергии происходит преимущественно на близко расположенных молекулах. Предложенная модель описывает также накопление вибрационной энергии молекулами CO, погруженными в аргон.
