The classical theory of stellar evolution predicts that low-mass stars are strong producers of ^{3}He, in contradiction with abundance observations of this element in Galactic HII regions and in the protosolar nebula. However in 2007, Charbonnel & Zahn showed that thermohaline mixing drastically reduces the yields of ^{3}He producted by low-mass red giants. Simultaneously this mechanism changes the surface of carbon isotopic ratio as well as the abundances of lithium, carbon and nitrogen. In this paper, we present and discuss models computed with the code STAREVOL that include the transport of chemical species in the radiative regions due to thermohaline instability and to rotational mixing. We compare our theorical predictions with recent observations.
