Air-broadened N2O line-shape parameters and their temperature dependences by requantized classical molecular dynamics simulations

•Air-broadened N2O line shapes were calculated using requantized classical molecular dynamics simulations.•The simulated spectra were fit with various line-shape models which include the first-order line mixing, providing the corresponding line-shape parameters for J′′ ≤ 59.•The temperature dependences of line-shape parameters were also deduced.•Comparisons with available experimental values show good agreements.
