Abstract
Building upon previous studies, we re-investigated the ethane spectrum between 1330 and 1610cm−1 by combining unapodized spectra obtained at room temperature with a Bruker Fourier transform spectrometer (FTS) in Brussels and at 131K with a Bruker FTS in Pasadena. The maximum optical path differences (MOPD) of the two datasets were 450 and 323.7cm, corresponding to spectral resolutions of 0.0020 and 0.0028cm−1, respectively. Of the 15,000 lines observed, over 4592 transitions were assigned to the ν6 (at 1379cm−1), ν8 (at 1472cm−1), ν4+ν12 (at 1481cm−1) and 2ν4+ν9 (at 1388cm−1) bands, and another 1044 transitions were located for the ν4+ν8−ν4 hot band (at 1472cm−1). Our new analysis included an improved implementation of the Hamiltonian calculation needed to interpret the complex spectral structures caused by numerous interactions affecting these four modes of vibration. From these results, we created the first line-by-line database containing the molecular parameters for over 20,000 12C2H6 transitions at 7μm.
