## Abstract The nitrogen NMR shielding of __tert__‐butyl isocyanide (1) is shown to be a sensitive probe of solvent polarizability–polarity, since the shielding is demonstrated to be unresponsive to hydrogen bonding effects between 1 and the solvent. The direction of solvent effects observed is exp
