The direct collisional energy transfer process Li*(3p) + CH4 → Li*(3s) + CH4 is investigated both theoretically and experimentally. We measured the nonreactive far-wing absorption profiles of the LiCH4 complexes by monitoring the Li(3s) → Li(2p) fluorescence at 812.6 nm. The intensity of the Li(3s) → Li(2p) fluorescence decreases with detuning, indicating a more efficient transition rate at low detuning. A high level ab initio calculation in both C2v and C3v symmetry is performed to provide a general picture of the nonradiative transition induced by collisions between lithium atoms and a methane molecule. |
