The frequency- and polarization-resolved degenerate resonant four-wave mixing (DFWM) spectra of the anisotropic states of the OH radicals produced by photolysis of H 2O2 by a planepolarized laser radiation at 266 nm are reported. The signals in the A 2 Σ + -X 2 Π(0,0) vibronic band were generated at the forward-box configuration with the photodissociation beam propagating along the box axis OZ[1]. The double and triple correlations between the dipole moment m of the dissociative transition in the parent molecule, the recoil velocity vand the angular momentum j of nascent particles –the key characteristics of the reaction path –were the main objectives of the study. To incorporate these correlations into a theoretical picture and to decouple the polarization factors from the molecular properties, the line-space approach was advanced. As a result, the DFWM intensities are expressed via the polarization factors, the Doppler-broadened profiles and the Einstein B-c
