    "abstract": "We discuss theoretically quantum interface between light and a spin polarized\nensemble of atoms with the spin \u003e= 1 based on an off-resonant Raman scattering.\nWe present the spectral theory of the light-atoms interaction and show how\nparticular spectral modes of quantum light couple to spatial modes of the\nextended atomic ensemble. We show how this interaction can be used for quantum\nmemory storage and retrieval and for deterministic entanglement protocols. The\nproposed protocols are attractive due to their simplicity since they involve\njust a single pass of light through atoms without the need for elaborate pulse\nshaping or quantum feedback. As a practically relevant example we consider the\ninteraction of a light pulse with hyperfine components of D1 line of 87Rb. The\nquality of the proposed protocols is verified via analytical and numerical\nanalysis.",
