Toward the understanding of the high resolution infrared spectrum of C2H6 near 3.3 μm

► First attempt to a global modeling of the 3.3 μm (2900-3071 cm−1) spectrum of 12C2H6. ► Analysis limited to the ν7 fundamental, including the perturbative effect of four states. ► A first iteration of a line-by-line database for the 3.3 μm spectrum generated.
