Dataset "Broadband spectroscopy of astrophysical ice analogues: IV. Optical constants of N2 ice in the terahertz and mid-infrared ranges"

Dataset of optical constants of solid N₂ in the IR and THz spectral ranges (0.3–16.0 THz), accepted for publication in A&A (https://arxiv.org/abs/2601.03951). The data file (.txt) is organized in columns as follows:frequency (f, THz), real part of the refractive index (n_re), absorption coefficient (alpha), real part of the dielectric function (eps_re), and imaginary part of the dielectric function (eps_im).
