Question

a. Deuterium is the isotope of hydrogen which contains a neutron as well as a proton, giving it a total atomic mass of 2.0144 a.m.u.

-Calculate the reduced mass (μ) for the D-³⁵Cl and H-³⁵Cl bonds.

-Calculate the vibrational frequency of these two bonds (wavenumber units), assuming that the force constant is 500 N/m.

b.The Raman spectrum of the mineral calcite consists of 3 very sharp lines, with shifts of 282, 713, and 1087 wavenumbers (cm^-1). Predict the wavelengths (nm) at which these lines will appear, if a sample of calcite is illuminated with an argon-ion laser (λ 488.0 nm).
