UV Luminance Spectroscopy Internal conversion is where None of these 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 excess electronic energy to vibrational energy A molecule converts its excess energy to light, and emits a photon None of these 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 excess electronic energy to vibrational energy A molecule converts its excess energy to light, and emits a photon ANSWER DOWNLOAD EXAMIANS APP
UV Luminance Spectroscopy Why phosphorescence measurements are usually made at a low temperature? To decease the efficiency of detector 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 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 ANSWER DOWNLOAD EXAMIANS APP
UV Luminance Spectroscopy Fluorescence occurs when a molecule lowers its vibrational energy by losing it's excess energy as a photon 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 None of these a molecule lowers its vibrational energy by losing it's excess energy as a photon 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 None of these ANSWER DOWNLOAD EXAMIANS APP
