Optional Bonus Problem 1 (Points: 1) Consider a state with a very short lifetime of 100 fs. Determine the natural linewidth broadening due to this finite lifetime. Give your answer in frequency and wavenumber. Optional Bonus Problem 2 (Points: 2) A methane (CH$_4$) molecule has C-H bond length of 108.7 pm and H-C-H bond angle of 109.5°. Which kind of a rotor is methane? How many unique moment of inertia does methane have? Determine the rotational constant for each unique moment of inertia for methane. Give your answer in wavenumbers. Optional Bonus Problem 3 (Points: 1) Acetone, (CH$_3$)$_2$CO, the molecule shown in Figure 1 has the following absorbance bands, obtained in infrared and ultraviolet-visible spectroscopy: 1. Strong absorbance at 1793 cm$^{-1}$ in the infrared spectrum. 2. Strong absorbance at 189 nm in the ultraviolet-visible spectrum. 3. Weak absorbance at 280 nm in the ultraviolet-visible spectrum. Assign each of the absorbance bands to a specific transition and to a specific group in the molecule.

7. Determine each of the following differential equations is linear or not. (a) \frac{d^2y}{dx^2} + 5\frac{dy}{dx} + 6y^2 = 0 (b) \frac{d^2y}{dx^2} + 5(\frac{dy}{dx})^3 + 6y = 0 (c) \frac{d^2y}{dx^2} + 5x^2\frac{dy}{dx} + 6y = 0 (d) \frac{d^2y}{dx^2} + 5y\frac{dy}{dx} + 6y = 0 (e) \frac{d^2y}{dx^2} + 5x\frac{dy}{dx} + e^x = 0 8. Solve the following differential equations: (a) Separable equation: \frac{dy}{dx} = y^2e^{-x} \frac{dy}{dx} = \frac{y+1}{xy^2}, \quad y(3e^2) = 2 (b) Homogeneous equation: \frac{dy}{dx} = \frac{x - y}{x + y} \frac{dy}{dx} = \frac{y^2}{x^2 + x} (c) Nearly homogeneous equation: \frac{dy}{dx} = \frac{2x - 5y - 9}{-4x + y + 9} \frac{dy}{dx} = \frac{3x + y - 1}{6x + 2y - 3} (d) Exact equation: (e^xsin(y) - 2x)dx + (e^xcos(y) + 1)dy = 0 (4y^4 + 3cos(x))dx + (16y^3x - 3cos(y))dy = 0
