Determine the symmetry point groups of the mer- and fac- isomers of the complex [Re(CO)3(NCMe)3] and deduce the irreducible symmetry representations generated by the three stretching vibrations of the C triple bond to N ligands in each of the isomers. [Regard NCMe as a linear ligand.] Also for each isomer discussed, state with reasoning which vibrations are IR active, and which are Raman active and how many bands will be observable in IR and Raman spectra. How can you distinguish the two isomers using their vibrational spectra?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
