  One of the most important problems in any conformal field theory is the
calculation of three-point functions of primary operators. In this paper we
provide explicit examples of correlators with two scalar operators in $\,{\cal
N}=4$ super-Yang--Mills theory at large $N$, corresponding to pulsating
semiclassical strings in AdS$_5\times S^5$, and an operator with small quantum
numbers at strong coupling.
