A hypothetical NH molecule makes a rotational-level transition from l = 3 to l= 1 and gives off a photon of wavelength 1.780 nm in doing so. What is the separation between the two atoms in this molecule if we model them as point masses? (The mass of hydrogen is 1.67 * 10-27 kg, and the mass of nitrogen is 2.33 * 10-26 kg).
What is the energy of a photon emitted from a CO molecule that transitions from the rotational Ji to Ji-1 level. Express your answer in units of ℏ^2/I, so you just have an integer value as a final answer.
