The mass of the deuterium molecule (D 2 ) is twice that of the hydrogen molecule (H 2 ). If the vibrational frequency of H 2 is 1.30 , 10 14 Hz, what is the vibrational frequency of D 2 ? Assume that the “spring constant” of attracting forces is the same for the two molecules. h θ L k M Figure P15.59 |
