distance spectral of the unitary cayley graphs of commutative rings

‎let $r$ be a commutative ring with unity $1neq 0$ and let $r^{times}$ be the set of ‎ all unit elements of $r$‎. ‎ ## ‎the unitary cayley graph of $r$‎, ‎denoted by $g_r=text{cay}(r,r^{times})$‎, ‎ ‎is a simple graph whose vertex set is $r$ and there is an edge between‎ two distinct vertices $x$ and $y$ if and only if $x-y in r^{times}$‎. ‎ ‎##this paper involves determining‎‎‎ ‎the distance‎, ‎distance laplacian and‎ ‎distance signless laplacian spectrum of the unitary cayley graphs with diameter at most $2$‎.
