Calculate the ratio of HBr molecules in the first excited vibrational state compared to the ground state at 800K. Remember that finding the probability of finding a molecule in a given state, i, is related to its energy, Ei, by the following equation: P(n) e^(-En/KT) You will need the following information to calculate the energy of the vibrational states: En = hv(n+1/2) for HBr v= 7.944*10^14s^-1 K=1.3807*10^-24J/K h=6.626*10^-34J*s
true/false 1. Energy of absorbed photon equals energy of emitted photon. 2. Following emission, molecule returns to its lowest energy state by a series of rapid vibrational relaxations. 3. The lifetime of the excited vibrational states is about a femtosecond; the lifetime of the excited electronic state is generally longer than a nanosecond. 4. Photon absorption usually occurs when a molecule is in its ground electronic state.
