It has long been known that most stars exist in binary systems. More recent observations of stellar populations in nearby star forming regions indicate that they have binary fractions comparable to that of the field. Hence, we can think of binary stars as a ubiquitous property of star formation; in order to understand how stars are formed in Nature, we must understand how binary star systems are formed. I will describe recent work we have pursued on models of molecular cloud cores which focus on the physical role turbulence plays in the process of star formation. These models have radii, masses, density contrasts, turbulent linewidths, projected velocity gradients, and aspect ratios consistent with observations of low-mass molecular cloud cores. I will present results of numerical simulations of these initial states, and argue that turbulence plays a critical role in the process of multiple star formation.
