Spectroscopy of two-photon transitions in C2H4 using the degenerate four-photon interaction method
Varakin V. N., Gordienko V. M.
Two-photon resonances with the overtone modes v7 and v8 of C2H4 are investigated by the degenerate four-photon interaction (DFI) method in an amplitude-polarization variant. The spectrum of multiphoton absorption (MPA) on the lines of the Ρ branch of the (00°1-10°0) band of the C02 laser is interpreted.
