Scaling Law of Quantum Confinement in Single-Walled Carbon Nanotubes - Supplemental Material

In our supplemental material document is presented the application of the inverse square root length scaling law to the lowest bright excited state transition in ultrashort (6,6) single-walled carbon nanotubes (SWCNTs), details of how the absorption spectra were calculated and plotted, visualizations of natural transition orbitals (NTOs) of the selected E11 states of (6,5) SWCNTs, and atomic coordinates of representative SWCNT models, including a model of a fluorescent ultrashort nanotube (FUN). All models and orbitals were visualized using GaussView.
