A New Near-Infrared Spectral Window for Cosmic Fullerenes: C60/C70 Combination Bands Beyond Tc 1

This dataset contains the complete anharmonic infrared transition inventories of C60 and C70 used in the manuscript “A New Near-Infrared Spectral Window for Cosmic Fullerenes: C60/C70 Combination Bands Beyond Tc 1.” The files include transition assignments, wavelengths, wavenumbers, photon energies, anharmonic infrared intensities, Einstein A coefficients, and wavelength-window classifications for overtone and combination-band transitions in the 3.3–5.2 μm region. Representative high-intensity transitions are summarized in Table 1 of the paper, while the full transition inventories are provided here for reproducibility.
