We develop a novel technique, applicable to numerical and experimental results alike, to detect large-scale turbulent structures in incompressible Rayleigh-Taylor mixing layers at low Atwood number. With results from Direct Numerical Simulations, we show that these structures are continuous along the turbulent mixing zones and exhibit a bimodal behaviour. The structures can therefore be categorized into two groups. This result strengthens the validity of the two-structure approach used in some turbulent mixing models.
