The two most widely studied families of high-temperature superconductors are TlBa{sub 2}Ca{sub n{minus}1}Cu{sub n}O{sub 3+2n} called 1-Tl(n) and Tl{sub 2}Ba{sub 2}Ca{sub n{minus}1}Cu{sub n}O{sub 4} + 2{sub n} called 2-Tl(n). The authors consider the structures of each family and show how some of the Raman active phonons are independent of n and some should have certain regularities depending on n. Further, the authors show which Raman active phonons should be essentially the same in both families of compounds.
