There are two main types of isotopes of Bromine in the nature, one is 79Br with the atomic mass of 79 amu, and another one is 81Br with the atomic mass of 81 amu. The force constant (k) of both the diatomic molecule H79Br and H81Br is 381 N/m. Assuming both molecules are harmonic oscillators.
(a) Calculate the fundamental vibrational frequency (ν) of H79Br. Report your value in Hz.
(b) Calculate the zero-point energy (E0) of H79Br. Report your value in J first, and then convert the unit to cm-1. Show both your calculation and unit conversion.

The two naturally occurring isotopes of bromine are 81Br (80.916 amu, 49.31%) and 79Br (78.918 amu, 50.69%). The two naturally occurring isotopes of chlorine are 37Cl (36.966 amu, 24.23%) and 35Cl (34.969 amu, 75.77%). Bromine and chlorine combine to form bromine monochloride, BrCl. What are the masses of the four different BrCl molecules? Express the masses in atomic mass units using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.
