a) For a heteronuclear diatomic molecule, depict an energy level diagram showing the four lowest rotational energy levels. Indicate the energy of each level in terms of B. Indicate all possible light absorption transitions.
b) Describe a spectrum absorbance vs. frequency corresponding to the transitions you have shown in part a. Indicate which transitions in the energy level diagram correspond to which peaks in the spectrum.
Assuming that teh F-18 can be transported at 58.0 miles/hour, how close must the hospital be to the cyclotron if 63% of the F-18 produced is to make it to the hospital
Calculate the pH of the solution that results when 20 ml of 0.100 M CH3COOH is mixed with 10.00 mL 0.200 M NaOH
Consider 1.70 mol of carbon monoxide and 3.00 mol of chlorine sealed in a 3.00 L container at 476 oC. The equilibrium constant, Kc, is 2.50 (in M-1) for CO(g) + Cl2(g) = COCl2(g), Calculate the equilibrium molar concentration of CO.
