9413242 Prasad Dr. Prasad will elucidate the observed molecular composition of interstellar clouds through evolutionary chemical-dynamical models. In contrast to most previous equilibrium chemical models which assume fixed physical conditions, the proposed models will account for the fundamental interaction between the chemistry and dynamics. It is expected that the new models can better clarify: (1) The processes by which a given cloud can attain its present state; (2) how it will further evolve with time, and (3) the growing difficulties that are confronting current static pseudo-time-dependent gas phase chemical models. This award is under the Small Grants for Exploratory Research program at NSF.

9413242 Prasad博士将通过演化化学动力学模型阐明观测到的星际云的分子组成。与大多数假设固定物理条件的平衡化学模型相比，所提出的模型将考虑化学和动力学之间的基本相互作用。预计新的模式可以更好地澄清：（1）一个给定的云可以达到其目前的状态的过程;（2）它将如何进一步随时间演变，以及（3）目前的静态伪时间依赖的气相化学模式所面临的日益增长的困难。该奖项是根据美国国家科学基金会探索性研究计划的小额赠款。
