A triatomic molecule has 9 degrees of freedom, in general. There are 3 translational modes, 3 rotational and 3 vibrational.
Diatomic GAS A molecule of diatomic gas has five degrees of freedom (3 tanslational and 2 rotational).
for polyatomics?
A polyatomic molecule may have either two or three rotational degrees of freedom, depending on the geometry of the molecule. For a linear polyatomic, such as CO2 or C2H2, the molecule has only two rotational degrees of freedom.
