For two knots [Formula: see text] and [Formula: see text], [Formula: see text] is said to be [Formula: see text]-adjacent to [Formula: see text], if [Formula: see text] admits a knot diagram containing [Formula: see text] crossings such that crossing changes at any non-empty subset of them yield a knot diagram of [Formula: see text]. Using a surgical view of Alexander invariants, we will characterize the Alexander polynomials of knots which are [Formula: see text]-adjacent to the trivial knot.
