Chemistry 508: Chemical Kinetics and Reaction Dynamics

Kubarych Group. In the Winter term of , I will be teaching Chem for the first time. That is, we will consider time-dependent phenomena in chemistry in many contexts. This approach will allow us to look at kinetics including barrier crossings, transition state theory, Kramers theory, and modern modifications of these. We never want to loose a molecular picture—in fact we want to celebrate and refine our molecular pictures—so we will look at reaction dynamics as well. The course will aim to make extensive connections between theory and experiment.

The transition state is a key concept in the field of chemistry and is important in the study of chemical kinetics and reaction dynamics. Recent experimental and theoretical advances in transient reaction dynamics probed by photodetachment of polyatomic anions are reviewed. This article reviews the fundamentals of variational transition state theory VTST , its recent theoretical development, and some modern applications. This review surveys quantum scattering calculations on chemical reactions of polyatomic molecules in the gas phase published in the last ten years. A range of ion—molecule reactions have been studied in the last years using the crossed-beam ion imaging technique, from charge transfer and proton transfer to nucleophilic substitution and elimination. We review the theories and simulations that have recently been developed to address and understand a new reaction phenomenon called roaming. Experimental and computational studies of chemical dynamics in solution explore how a solvent modifies reaction mechanisms.

The overall objective of this chapter is to understand macroscopic properties such as pressure and temperature on a microscopic level. We will find that the pressure of an ideal gas can be understood by applying Newton's law to the microscopic motion of the molecules making up the gas and that a comparison between the Newtonian prediction and the ideal gas law can provide a function that describes the distribution of molecular velocities. This distribution function can in turn be used to learn about the frequency of molecular collisions. Since molecules can react only as fast as they collide with one another, the collision frequency provides an upper limit on the reaction rate. The outline of the discussion is as follows. The speed distribution is closely related to the distribution of molecular energies, G [member of] d[member of].

By Paul L. The overall objective of this chapter is to understand macroscopic properties such as pressure and temperature on a microscopic level. This distribution function can in turn be used to learn about the frequency of molecular collisions. Since molecules can react only as fast as they collide with one another, the collision frequency provides an upper limit on the reaction rate. The outline of the discussion is as follows. Finally, we will use the velocity distribution to calculate the number of collisions Z that a molecule makes with other molecules in the gas per unit time. Since in later chapters we will argue that a reaction between two molecules requires that they collide, the collision rate Z provides an upper limit to the rate of a reaction.

Увы, у этой программы такого тщеславия нет, у нее нет инстинкта продолжения рода. Она бесхитростна и целеустремленна, и когда достигнет своей цели, то скорее всего совершит цифровое самоубийство.  - Джабба театральным жестом указал на громадный экран.

 - Она еще раз взглянула на текст.  - Элементы, ответственные… У Дэвида Беккера, находившегося в трех тысячах миль от комнаты оперативного управления, загорелись. - Элементы! - воскликнул.  - Мы говорим о математике, а не об истории.

Скорее бы просигналил ее терминал. Но тот молчал. Конец лета. Солнце уже зашло. Над головой автоматически зажглись лампы дневного света.

Последний из трех миллионов процессоров размером с почтовую марку занял свое место, все программное обеспечение было установлено, и керамическая оболочка наглухо заделана. ТРАНСТЕКСТ появился на свет. Хотя создававшийся в обстановке повышенной секретности ТРАНСТЕКСТ стал плодом усилий многих умов и принцип его работы не был доступен ни одному человеку в отдельности, он, в сущности, был довольно прост: множество рук делают груз легким.

Беккер вздохнул, взвешивая свои возможности. Где ей еще быть в субботний вечер.
