Q 1(a) Methane, CH4 is a tetrahedral molecule and does not exhibit a permanent dipole moment (i.e. it has a dipole moment of 0). Nonetheless, in microwave spectroscopy methane does exhibit a weak, but measurable absorbance. Explain why you think this is the case? Q 1(b) The diatomic molecule 12C32S has been detected in interstellar gas clouds by microwave spectroscopy. The masses of the two atoms are C = 12.00 amu and S= 31.972 amu and 12C32S has an equilibrium bond length of 1.534 Å. Predict which rotational transition in 12C32S will have the greatest population at a temperature of 85 K.
