A hydrogen atom of mass 1.67 x 10 27 kg is attached to a very large'protein by a bond that behaves much like a spring. (a) If the vibrational frequency of the hydrogen is 1.0 x 10 14 Hz, what is the “effective” force constant of this spring-type bond? (b) If the total vibrational energy is kT (k is Boltzmann’s constant), approximately what is the classical amplitude of vibration at room temperature? By comparison, the diameter-of a hydrogen atom is about 10 -10 m ?
