The term 'degrees of freedom' is ambiguous. In dynamics, and actually in most areas, it means the number of independent parameters needed to describe the system. These can be expressed in different ways (such as cartesian or polar co-ordinates) but the number is always the same. So a diatomic molecule has 6. WebThe corresponding degree of freedom is said to be frozen out; this is the situation for the vibrational degrees of freedom at room temperature and that is why the usual assumption is that they will not contribute.
