The role of quantum mechanical coherences or coherent superposition states in excited state processes has received considerable attention in the last two decades largely due to advancements in ultrafast laser spectroscopy. These coherence effects hold promise for enhancing the efficiency and robustness of functionally relevant processes, even when confronted with energy disorder and environmental fluctuations. Understanding coherence deeply drives us to unravel mechanisms and dynamics controlled by order and synchronization at a quantum mechanical level, envisioning optical control of coherence to enhance functions or create new ones in molecular and material systems. In this frontier, the interplay between electronic and vibrational dynamics, specifically the influence of vibrations in directing electronic dynamics, has emerged as the leading principle. Here, two energetically disparate quantum degrees of freedom work in-sync to dictate the trajectory of an excited state reaction. Moreover, with the vibrational degree being directly related to the structural composition of molecular or material systems, new molecular designs could be inspired by tailoring certain structural elements.

从一致性到功能：探索化学系统中的连接
量子力学相干性或相干叠加态在激发态过程中的作用在过去二十年中受到了相当多的关注，这主要归功于超快激光光谱学的进步。即使面临能量紊乱和环境波动，这些相干效应也有望提高功能相关过程的效率和稳健性。对相干性的深刻理解促使我们在量子力学水平上解开由秩序和同步控制的机制和动力学，设想对相干性进行光学控制以增强功能或在分子和材料系统中创建新功能。在这一前沿领域，电子动力学和振动动力学之间的相互作用，特别是振动对电子动力学的影响，已成为主导原则。在这里，两个能量不同的量子自由度同步工作，以决定激发态反应的轨迹。此外，由于振动程度与分子或材料系统的结构组成直接相关，因此可以通过定制某些结构元素来激发新的分子设计。
