Methane, CHa is a tetrahedral molecule and does not exhibit a pemanent 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? a 1(b) [40 Marks) The diatomic molecule 12CS 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 1c$ has an equilibrium bond length of 1.534 A. Predict which rotational transition in 1CS will have the greatest population at a temperature of 85 K.
