I consider semi-classical type IIA strings rotating in the AdS(4) part of AdS4 x CP3. The one loop sigma model corrections to this classical solution are used to compute the energy shift, and the result is found to be E - S = f(lambda) ln S with f(lambda) = root 2 lambda-5ln2/2 pi + O(1/root lambda). Even though the functional forms match, the actual numerical value of this one loop string result di ff ers from the result obtained on the integrable N = 6 Chern-Simons (ABJM) theory side.
