摘要: We present analytical signal expressions for each two-color resonant four-wave mixing (TC-RFWM) scheme that can be used double-resonance molecular spectroscopy in the limit of weak fields (no saturation). The theoretical approach employs time-independent, diagrammatic perturbation theory and a spherical tensor analysis an extension recent treatments degenerate [S. Williams, R. N. Zare, L. A. Rahn, J.

Under assumption relaxation population, orientation, alignment are same, simple analytic derived commonly experimental configurations. is found to product concentration term, one-photon line shape function, laboratory-frame geometric factor. These intended facilitate practical TC-...
