Dynamics of Molecules in Excited States
Page • When molecules absorb visible or ultraviolet light, they are promoted to an excited state in which the electrons of the molecule occupy different orbitals. This process is critical not only to life on Earth (e.g., photosynthesis), but also to human interactions (e.g., vision). We seek to understand the fundamental details...
