ExoMol. XXVII: spectra of C2H4

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.
