We measure the electron Lande g-factor and electron spin lifetime in (110)-oriented GaAs quantum wells by time- and polarization resolved photoluminescence spectroscopy. The electron Lande g-factor shows an anisotropy on the in plane magnetic field direction and this anisotropy is investigated in detail for different quantum well widths. Furthermore, the electron spin dynamics is determined in dependence on quantum well widths and spin orientation.
