Doppler profiles of the Degenerate Resonant Four-Wave Mixing (DFWM) spectral
responses from rapidly recoiling products of photodecomposition by plane-polarized radiation
are theoretically studied. Emphasis is placed on the shapes produced by rotational helicity when
orientations of the angular momenta and the recoil velocities of nascent particles are correlated.
Illustrations are provided for cases when a decay of resonating states tangibly affects the helicityinduced DFWM profiles.
