Research output: Contribution to journalArticle


The temperature dependence of picosecond CARS of vibrational excitons in naphthalene is presented. Below ≈40 K relaxation is dominated by spontaneous emission of phonons. Above 40 K high-frequency phonons induce dephasing. The results are consistent with a phonon-promoted energy transfer process.
