9800555 Dalgarno Dr. Dalgarno at Harvard University will direct a theoretical project to carry out quantum-mechanical calculations of the rate coefficients for rotational and vibrational energy transfer in collisions of hydrogen and helium atoms with molecular hydrogen. These processes are critical to the interpretation of the red and infrared emission spectra of molecular hydrogen, and they control the cooling in a wide range of environments. Similar calculations on collisions of hydrogen with carbon monoxide will be performed. ***

9800555 Dalgarno 哈佛大学的 Dalgarno 博士将指导一个理论项目，对氢和氦原子与氢分子碰撞时旋转和振动能量转移的速率系数进行量子力学计算。 这些过程对于解释氢分子的红色和红外发射光谱至关重要，并且它们控制着各种环境中的冷却。 将对氢气与一氧化碳的碰撞进行类似的计算。 ***
