An empirical line list for methane near 1µm (9028–10,435cm−1)

The highly congested absorption spectrum of methane near 1µm was recorded by Fourier Transform Spectroscopy at room temperature. The detectivity threshold of the recordings corresponds to an intensity cut off on the order of 2×10−26cm/molecule. An empirical line list is constructed for the 9028–10,435cm−1 spectral region. It consists of (i) 7212 lines in the 9520–10,435cm−1 interval corresponding to the tetracontad and (ii) 574 lines in the 9028–9200cm−1 interval corresponding to the high energy region of the triacontad, dominated by the 3ν3 band near 9046cm−1. The first line list fills an important gap in the HITRAN database. The obtained data set constitutes a solid basis for future rovibrational assignments on the basis of advanced theoretical methods. •The FTS methane absorption spectrum is recorded near 1µm.•The first empirical line list is constructed in the tetracontad (9523–10,435cm−1).•The 3ν3 region near 9047cm−1 (9028–9200cm−1) is revisited.
