Time‐resolved diode laser absorption spectroscopy has been used to study vibrational‐to‐vibrational energy transfer from highly excited azulene and azulene‐d8 to carbon dioxide. The energetic azulene molecules were prepared by internal conversion (S2→S0) after excitation into the S2 state by a pulsed laser source of 337 nm photons. Relative populations of CO2 vibrational modes were determined and compared with predictions of a statistical model. The total vibrational energy transferred to CO2 was determined to be about 25% of the initial azulene energy. Similar experiments were carried out using 248 nm photons to excite azulene in the region of the S4 state.
