Vibrationally resolved emission of thiophosgene dimer

► It is found that the fifth electronic excited state of symmetry B2u is the lowest electronic excited state with nonzero oscillator strength. It was thought to be the second electronic excited state. ► The lowest frequency vibration of thiophosgene dimer was assigned at a much lower energy than previously. ► The two lowest vibrations of thiophosgene dimer are weakly coupled.
