A linear molecule, its two carbons are joined by a triple bond and have terminal fluorines : F-Ca " C-F . The molecule is the perfluorocarbon analog of acetylene, C 2 H 2.

To determine the "'vibrational spectroscopy of linear molecules "', the rotation and vibration of linear molecules are taken into account to predict which vibrational ( normal ) modes are active in the Raman spectrum.

For any given chemical compound, there are a total of 3N Linear molecules only have two rotations because rotations along the bond axis do not change the positions of the atoms in the molecule.
35.
For molecules with N number of atoms, linear molecules have 3N 5 degrees of vibrational modes, whereas nonlinear molecules have 3N 6 degrees of vibrational modes ( also called vibrational degrees of freedom ).
36.
In general, then, there will be three additional degrees of freedom corresponding to the rotational motion of the molecule, ( For linear molecules one of the inertia tensor terms vanishes and there are only two rotational degrees of freedom ).
37.
For example, triatomic nitrous oxide N 2 O will have only 2 degrees of rotational freedom ( since it is a linear molecule ) and contains n = 3 atoms : thus the number of possible vibrational degrees of freedom will be.
38.
Once the point group of the linear molecule is determined and the correlated symmetry is identified, all symmetry element operations associated to that correlated symmetry's point group are performed for each atom to deduce the reducible representation of the 3 " N"
39.
Eigenvalues of the Teller showed that excepting linear molecules there are always first-order terms in an expansion of the matrix elements of the Hamiltonian in terms of symmetry-lowering ( in the language of group theory : non-totally symmetric ) normal modes.

According to Last and George, the Xe Cl Xe linear molecule ought to have produced an emission approaching the ground state at 321 nm and the transition moment should be elevated to 3.9 D . As of 2014, however, no experiment confirms this prediction.
