Single crystals untwinned optimally doped YBa{sub 2}Cu{sub 3}O{sub 9.65} show a large degree of anisotropy in a-b plane properties such as resistivity, infrared conductivity and value of zero temperature penetration depth. This source of orthorhombicity must ultimately reside in the CuO chains. Using a three plane model; 2 CuO{sub 2} and one CuO (chain plane), the authors study solutions of three coupled BCS equations which include inter- as well as intra-plane coupling. The gaps are found to contain s- as well as d-wave symmetries. From their solutions, the authors calculate the penetration depth and compare with experiments.
