Pseudoline parameters to represent n-butane (n-C4H10) cross-sections measured in the 7–15 µm region for the Titan atmosphere

•Obtained 28 spectra of n-C4H10 at 180 – 298 K from 650 to 1538 cm−1 using a FT-IR at JPL.•Derived cross-sections of n-C4H10 as a function of wavenumber and temperature.•Generated pseudoline lists to represent the observed spectra to within 5% or better.•Measured integrated intensities to be 5.06(28), 7.18(27), 0.91(4), and 49.01(20) × 10−19 cm−1/(molecule.cm−2) in the 660–860, 860–1060, 1060–1200, and 1200–1538 cm−1 regions respectively.
