The formation, energy transfer processes, and chemical reactions of the ozone excited states will be investigated and a kinetic model of these processes, based upon the experimental results, will be constructed. Specifically, they plan to measure the wavelength dependence of the absolute quantum yields as functions of wavelength, pressure, gas composition, and temperature, and to investigate chemical reactions of the excited ozone states. The research is motivated by the need to assess the potential atmospheric importance of ozone excited states which cannot be accomplished until the states, the quantum yields for production, the wavelength dependencies, the products of the quenching steps, the connections among the several observed states, and the rate coefficients for the elementary reactions have been identified.

将研究臭氧激发态的形成、能量转移过程和化学反应，并根据实验结果构建这些过程的动力学模型。 具体来说，他们计划测量绝对量子产率与波长、压力、气体成分和温度的函数关系，并研究臭氧激发态的化学反应。 这项研究的动机是需要评估臭氧激发态对大气的潜在重要性，只有在状态、生产的量子产率、波长依赖性、猝灭步骤的产物、几个观察到的状态之间的联系、并确定了基元反应的速率系数。
