Nonadiabatic effects are ubiquitous in photophysics and photochemistry, and therefore, many theoretical developments have been made to properly describe them. Conical intersections are central in nonadiabatic processes, as they promote efficient and ultrafast nonadiabatic transitions between electronic states. A proper theoretical description requires developments in electronic structure and specifically in methods that describe conical intersections between states and nonadiabatic coupling terms. This review focuses on the electronic structure aspects of nonadiabatic processes. We discuss the requirements of electronic structure methods to describe conical intersections and nonadiabatic couplings, how the most common excited state methods perform in describing these effects, and what the recent developments are in expanding the methodology and implementing nonadiabatic couplings.

描述非绝热效应和锥形交叉点的电子结构方法

非绝热效应在光物理学和光化学中无处不在,因此,已经进行了许多理论发展来正确描述它们。锥形交叉点是非绝热过程的核心,因为它们促进电子态之间的高效和超快非绝热跃迁。正确的理论描述需要电子结构的发展,特别是描述状态和非绝热耦合项之间的锥形交叉点的方法。本综述侧重于非绝热过程的电子结构方面。我们讨论了描述锥形交叉点和非绝热耦合的电子结构方法的要求,最常见的激发态方法在描述这些效应时的表现,
