Absorption cross sections for neopentane broadened by nitrogen in the 3.3 µm region

•High resolution absorption spectra of neopentane, C(CH3)4, in the 3.3 µm region (2550-3350 cm-1).•Cross sections for neopentane broadened by N2.•Measurements performed for 202-297 K.•Useful for analysis of spectra of Titan. Infrared absorption spectra of neopentane, 2,2-dimethylpropane, C(CH3)4, were recorded in the 2550-3350 cm-1 region by high resolution Fourier transform spectroscopy at the Canadian Light Source (CLS). Absorption cross sections were obtained for pure samples and with nitrogen as a broadening gas for 4 temperatures (202, 232, 265, 297 K).
