A quantum treatment on ICN photodissociation from an initial parallel transition (Ω′ = 0 ← Ω″ = 0) to 1 the asymptote CN(|)+ I( 2 P 1/2 ) is presented. Density matrices of both photofragments are derived, and explicit expressions of the state multipoles in terms of the angular momentum coupling coefficients and the rotation‐bending factors have been obtained. The present theoretical framework provides a foundation to study photofragments with non‐null electronic and/or spin angular momenta. To investigate the angular momentum polarizations phenomena, these density matrices can play a prime role in laser‐based detections of state‐selected photofragments.
