SUMMARY
The discussion focuses on determining the sigma and pi orbitals of the C2H4 molecule using group theory and symmetry principles. The D2h point group is identified as the correct symmetry group for C2H4, despite its lack of two-dimensional irreducible representations necessary for pi orbitals. The reference to "Infrared and Raman Spectra" by Herzberg confirms the use of D2h symmetry in this context. The user seeks recent scientific articles on C2H4's structure, particularly those utilizing group symmetry, noting the scarcity of contemporary research beyond historical works by Mulican (1933) and Lennard-Jones (1950).
