6.
Internal conversion is where
the spin of an excited electron reverses, changing the state of the molecule (from singlet state to triplet state or vice versa)
A molecule converts its excess energy to light, and emits a photon
A molecule converts excess electronic energy to vibrational energy
none of the above

7.
Why phosphorescence measurements are usually made at a low temperature?
To prevent thermal degradation of the phosphorescent species
To promote phosphorescence by slowing the rate of radiationless transfer processes
To increase the efficiency of the detector
To decease the efficiency of detector

Fluorescence occurs when
a molecule returns to the electronic ground state from an excited triplet state by losing it's excess energy as a photon
a molecule returns to the electronic ground state from an excited singlet state by losing it's excess energy as a photon
a molecule lowers its vibrational energy by losing it's excess energy as a photon
none of the above
