<p style="text-align: justify;"><span style="font-size: 12.16px;">Study of systems such as water under confined conditions is actively pursued because of its relevance to real systems, such as cells, microorganisms, etc. In this regard, EPR spectroscopy offers a convenient route due to its excellent sensitivity to micro viscosity and penetrability power.  When used as a probe-based spectroscopy, however, the probe-system interactions need to be thoroughly examined beforehand. In this work, we consider a specific property: solid⇌liquid transition of water, and ask a fundamental question, “Can EPR detect the freezing of water at its conventional freezing point in bulk/confined conditions?”   Our work convincingly demonstrates that the spin probe can itself induce liquid domains in ice, which could be mistaken as a depression in the freezing point. We propose a theory to account for these solute induced perturbations. Finally, it will be discussed how the proposed theory can be applied to the extreme dilution case of a solution containing a single solute molecule.   </span></p>
