OSE 5312 FUNDAMENTALS OF OPTICAL SCIENCE Spring 2008 Homework set 6: Due Wed, March. 5 1. Starting from the Debye equation, derive expressions for χ’(ω) and χ”(ω), for a liquid made up of molecules with permanent dipole moment. Methanol is a liquid composed of 1028 polar molecules per m3, each with a dipole moment of 1.7 Debyes (1 Debye = 3.35 x 10-30 C m), and a relaxation time of 50 ps. Taking the high frequency (compared to frequencies relevant to hindered rotational modes) dielectric constant, ε∞ = 2.1, plot χ’(ω), χ”(ω), n(ω) and κ(ω) vs. ω for methanol at T=300 K.

3. A diatomic molecule has atomic masses 4 amu and 10 amu. The atoms are spaced by distance x and the potential energy well they sit in is found to be adequately described by: U(x) = {1(Å5)/x10-1/x5} ⋅2 (kg Å7/s2) where x is in Å. Find the equilibrium spacing, xo. Determine the range over which the potential approximates a harmonic potential, and find the natural vibrational frequency of the molecule in this range.
