Abstract
Let (Formula presented.) denote a unitary one-matching bi-Cayley graph over a finite commutative ring R. In this paper, we give a necessary and sufficient condition for (Formula presented.) (respectively, the complement of (Formula presented.) and the line graph of (Formula presented.)) to be Ramanujan.
