25. According to the image below answering all the questions. Each transition is labeled with a letter (A,B, etc) near its arrowhead. Each transition can be radiative, non-radiative, or both. (A) Select the arrow(s) that correspond to electronic excitation. (B) Select the arrow(s) that correspond to vibrational excitation. (C) Select the arrow(s) that correspond to IR absorption. (D) Select the arrow(s) that correspond to UV-visible absorption. (E) Select the arrow(s) that correspond to emission of a UV-visible photon. (F) Select the arrow(s) that correspond to thermal relaxation (non-radiative). (G) Select the arrow(s) that correspond to a chemical reaction (e.g. fragmentation). (H) Select the arrow(s) that correspond to intersystem crossing. All choosing options are the same as indicated below. -A -B -C -D -F -G -H
