<P> Another type of motion of a diatomic molecule is for each atom to oscillate--or vibrate--along the line connecting the two atoms . The vibrational energy is approximately that of a quantum harmonic oscillator: </P> <Dl> <Dd> <Dl> <Dd> E v i b = (n + 1 2) ħ ω n = 0, 1, 2,...(\ displaystyle E_ (vib) = \ left (n+ (\ frac (1) (2)) \ right) \ hbar \ omega \ \ \ \ \ n = 0, 1, 2,...\,) </Dd> </Dl> </Dd> <Dd> where <Dl> <Dd> n (\ displaystyle n) is an integer </Dd> <Dd> ħ (\ displaystyle \ hbar) is the reduced Planck constant and </Dd> <Dd> ω (\ displaystyle \ omega) is the angular frequency of the vibration . </Dd> </Dl> </Dd> </Dl> <Dd> <Dl> <Dd> E v i b = (n + 1 2) ħ ω n = 0, 1, 2,...(\ displaystyle E_ (vib) = \ left (n+ (\ frac (1) (2)) \ right) \ hbar \ omega \ \ \ \ \ n = 0, 1, 2,...\,) </Dd> </Dl> </Dd> <Dl> <Dd> E v i b = (n + 1 2) ħ ω n = 0, 1, 2,...(\ displaystyle E_ (vib) = \ left (n+ (\ frac (1) (2)) \ right) \ hbar \ omega \ \ \ \ \ n = 0, 1, 2,...\,) </Dd> </Dl>
