Interpretation:
The effect of the involvement of orbitals for sulfur on the symmetry-adapted linear combination of molecular orbitals for hydrogen sulfide is to be stated.
Concept introduction:
Symmetry-adapted linear combination is referred to as the wavefunction of the symmetry equivalent orbitals. The symmetry-adapted linear combination is used to determine the binding schemes and symmetries of the molecule. The SALC’s are determined with the help of character tables and great orthogonality theorem.
