在 Hollenbach 等人的模型中。 （1971），氢分子在颗粒上形成。氢分子通过吸收莱曼带中的辐射而被破坏。已经对分子氢的形成和破坏速率进行了研究。计算了紫外线辐射场以确定莱曼带吸收导致的分子氢破坏率。对氢分子形成速率上限的估计是通过对观测到的氢分子非常少的恒星进行的观测而获得的。
In the model of Hollenbach et al. (1971), hydrogen molecules are formed on grains. Molecular hydrogen is destroyed by absorption of radiation in the Lyman bands. A study has been conducted regarding the formation and destruction rates of molecular hydrogen. The ultraviolet radiation field has been calculated to determine the rate of molecular hydrogen destruction resulting from absorption in the Lyman bands. An estimate of an upper limit for the molecular hydrogen formation rate is obtained from observations involving stars in which very little molecular hydrogen is observed.
