The C-H bond in ethanol vibrates at a
frequency of 3000 cm ¹. What frequency (s
1) of light is required to change the
vibrational quantum number from v=0 to
v=1, assuming that C-H acts as a harmonic
oscillator.
An aqueous solution of chloroethanoic acid at 25oC is irradiated with light of wavelength 253.7 nm. As a consequence, a photochemical reaction occurs where 2-hydroxyethanoic acid and hydrogen chloride are obtained. It is observed that when 34.37 J are absorbed, 2.325·10-5 moles of chlorine ion are formed.
a) Wwtermine the number of Einsteins absorbed
c) calculate the quantum yield of the reaction.
A molecule can have various types of energies (translational, rotational, vibrational, and electronic), the sum of which is the
molecule's total energy.
E trans = (n +n + n²)
Erot = J (J + 1)

In the equations, nx, ny, nz, J, and u are quantum numbers, h is Planck's constant, m is the mass of the molecule, V is the
volume of the container, I is the moment of inertia of the molecule, and v is the fundamental vibration frequency.
For carbon monoxide, CO, the moment of inertia is I = 1.45 x 10-46 kg-m², and the fundamental vibration frequency is
v = 2130 cm-¹. Let V = 12.5 L, and let all the quantum numbers be equal to 1.
Calculate the translational, rotational, and vibrational energies per mole of CO for these conditions.
