The vibration frequency for the molecule HF is 1.24 x 1014 Hz. The mass of a hydrogen atom is 1.67 x 10-27 kg, and the mass of a fluorine atom is 3.15 x 10-26 kg.
(a) What is the force constant k' for the inter atomic force?
(b) What is the spacing between adjacent vibrational energy levels in joules and in electron volts?
(c) What is the wavelength of a photon of energy equal to the energy difference between two adjacent vibrational levels? In what region of the spectrum does it lie?
