Using moving frame method, we study the Möbius geometry of a pair of conformally immersed surfaces in . Two new invariants θ andρassociated with them arise naturally as well as the notion of touch and co-touch. As an application, adjoint transform is defined for any Willmore surface in . It always exists locally, hence generalizes known duality theorems of Willmore surfaces. Finally we characterize a pair of adjoint Willmore surfaces in terms of harmonic map.
