Abstract

We are studying 46 Grand Design spirals widely spread in types, which have been imaged in the K-band with the ESO NTT telescope. Eleven objects show knots strongly associated to the m = 2 Fourier component of the spiral structure. Corotation ressonance (CR) for the two-armed pattern have been derived for five galaxies.
