Description
A hot line list is presented for ^12^C_2_H_4_ in its ground electronic state. This line list, called MaYTY, contains 50 billion transitions and should be complete for temperatures up to 700K. It covers the wavelengths up to 7000cm^-1^ and rotational excitation up to J=78. The line list was computed using the eigenvalues and eigenvectors of C_2_H_4_ obtained by variational solution of the Schrodinger equation for the rotation-vibration motion of nuclei employing the program TROVE and a new 'spectroscopic' potential energy surface (PES) obtained by refining an ab initio PES (CCSD(T)=F12b/cc-PVTZ) in a least-squared fit to the experimentally derived energies with J=0,1 as extracted from the literature (Georges R., Bach M., Herman M., 1999, Mol. Phys., 97, 279) and HITRAN database. The dipole transition probabilities are represented by the Einstein-A coefficients obtained using a new ab initio dipole moment surface (CCSD(T)-F12b/aug-cc-pVTZ).
