According to the vibrational rotation spectrum of the H³⁵Cl molecule, the vibrational wave number was found to be 2988.9 cm^-1.

Find the approximate zero point energy and dissociation energy for HD and D₂ ?, For ³⁹K³⁵Cl, the most intense line in the far infrared spectrum is found at 378.0 cm^-1. Find the force constant and the rotation period. Since the force constant for ⁷⁹Br₂ is 240 N/m, find the fundamental vibration frequency and zero point energy.
