Spectroscopy relies on the excitation and relaxation of electrons. Which of the following statements about spectroscopy is true? Phosphorescence is the emission of a photon of light as an electron transitions from the excited singlet state to ground state. Collisional deactivation of an excited molecule decreases the absorbance response. Molecular absorption spectrometry measures the change in light intensity as light passes through a sample. Fluorescence is the absorption of a photon of light as an electron transitions from the ground state to an excited triplet state.
