## Angular velocity correlations for rough spheres are examined via a slip boundary condition. This condition approsimateIy accounts for microscopic boundary layer effects and exposes both microscopic and collective decay effects The results compare well with molecular dynamics calculations.

β¦ Synopsis
A renormalized kinetic theory for molecular fluids is used to construct the linear and angular velocity correlation functions for rough sphere fluids. Results are compared with recent molecular dynamics experiments.
