2. Molecules absorb IR radiation consistent with vibrational energy and rotational energy. Which of these is
present in condensed phases (liquid, solution, solid)?
. Figure 8–59 illustrates an H,O molecule. The O-H bond
length is 0.096 nm and the H- 0-H bonds make an
angle of 104°. Calculate the moment of inertia of the H2O
molecule (assume the atoms are points) about an
axis passing through the center of the oxygen
atom (a) perpendicular to the plane of the
molecule, and (b) in the plane of the molecule,
bisecting the H-0-Hbonds.

7. Consider the Jablonski diagrams below, where So, S₁, and S2 are all singlet electronic
states, and T₁ is a triplet electronic state. (So is the electronic ground state.) The horizontal
lines indicate the vibrational energy levels in each electronic state. The arrow drawn on the
diagram represents the absorption of a UV photon with = 250 nm, promoting the
molecule to a high vibrational level in the S₁ state. (The wavelength values here and below
are meant as a guide, but this is not really a quantitative question.)
Two different processes are described below the diagrams. Read each one, and then draw
an appropriate set of arrows on the corresponding diagram to represent the process
described.
