![]() These metallic and nonmetallic C 120 fullertube isomers open the door to both fundamental research and application development. Identification of isomers I and II was surprisingly facile, i.e., two purified isomers for two possible structures of widely distinguishing features. Just to avoid any unnecessary time-wastes, i wanted to ask if there is a way to import the Steam installation of the game into ARC (tried the laucher.exe without success). From 10 774 mathematically possible IPR C 120 structures, this anisotropic polarizability paradigm is quite favorable to distinguish tubular structures from carbon soot. Frankly, i would have to download Gigantic again which would take quite some time with my slow as internet. With microgram quantities not amenable to crystallography, we demonstrate that DFT anisotropic polarizability, augmented by long-accepted experimental analyses (HPLC retention time, UV–vis, Raman, and STM) can be synergistically used (with DFT) to down select, predict, and assign C 120 fullertube candidate structures. STM imaging reveals a tubular structure with an aspect ratio consistent with a C 120-D 5d(1) fullertube. These structural assignments are further supported by Raman data showing metallic character for C 120-D 5d(1) and nonmetallic character for C 120-D 5h(10766). C 120 isomer II matches a C 120-D 5h(10766) fullertube. ![]() Theoretical and experimental analyses of anisotropic polarizability and UV–vis assign C 120 isomer I as a C 120-D 5d(1) fullertube. Moreover, the C 120-D 5d(10766) fullertube has an end-cap derived from C 80-I h and is a new fullertube whose C 40 end-cap has not yet been isolated experimentally. This increase of 20 carbon atoms represents a gigantic leap in comparison to three decades of C 60–C 90 fullerene research. These new molecules represent the highest aspect ratio fullertubes isolated to date for example, the prior largest empty cage fullertube was C 100-D 5d(1). We report the first experimental characterization of isomerically pure and pristine C 120 fullertubes, C 120-D 5d(1) and C 120-D 5h(10766).
