The molecules can absorb and emit electromagnetic radiation, which corresponds to changes in their rotational energy. Consider a two-atom O2 molecule and its rotation.
a)Determine the moment of inertia of the molecule if it rotates
about its center. The distance of atoms in the molecule is d = 0.12
nm. (ANSWER IS : 1.9*10^-46 kgm^2
b)There is a transition from ℓ2 = 10 to ℓ1 = 9 in the molecule. Determine the energy of the associated photon?
(i need answer to part b )

Hydrogen gas can only absorb EM radiation that has an energy corresponding to a transition in the atom, just as it can only emit these discrete energies. When a spectrum is taken of the solar corona, in which a broad range of EM wavelengths are passed through very hot hydrogen gas, the absorption spectrum shows all the features of the emission spectrum. But when such EM radiation passes through room-temperature hydrogen gas, only the Lyman series is absorbed. Explain the...

For the wavelengths given for different bands of the electromagnetic spectrum, determine the energy of a single photon, indicate if it can break the atomic bond of water (4.7 eV), ionize hydrogen (13.6 eV), and ionize calcium (6.11 eV). For those that can break bonds, how many molecules/atoms can one photon change? Show all your work for microwaves and ultraviolet,...

Superman is in some ways a living solar battery; his cells absorb electromagnetic radiation from stars (like Earth's sun). The radioactivity of kryptonite possibly interferes with this process, driving the energy out of his cells in a painful fashion. Long term and high-level exposure to green kryptonite can be fatal to Superman. For this reason, Superman spends a significant amount of time studying kryptonite. He performs an experiment to determine its half-life. He begins with 1.5 mols of kryptonite atoms...
