  text: We present a general theoretical framework for helical dichroism (HD), establishing
    an explicit link between chiral resolution and orbital angular momentum (OAM)
    exchange in light–matter interaction. Tracing microscopic mechanisms of the OAM
    transfer, we derive rotational selection rules, which establish that HD emerges
    only from the spin–orbit coupling of light, even for beams without the far-field
    OAM. Our findings refine the conditions for observing HD, provide a tool to re-examine
    the outcome of prior experiments, and guide future designs for chiral sensing
    with structured light.
