Assertion: Each vibrational mode gives two degrees of freedom. Reason: By law of equipartition of energy, the energy for each degree of freedom in thermal equlibrium is 2k_(B)T.

Thus each vibriational mode gives 2 degrees of freedom i.e., kinetic and potential energy modes, corresponding to the energy `2((1)/(2)k_(BT))=k_(B)T.`</body></html>
