Abstract: Some quasi Grüss type inequalities for the Riemann-Stieltjes integral of continuous complex valued integrands defined on the complex unit circle C (0; 1) and various subclasses of integrators are given. Natural applications for functions of unitary operators in Hilbert spaces are provided.
