✦ Synopsis

We examine the condensed states for a semi exible polymer in poor solvent as a function of sti ness, focusing on the transition region between globule and torus. Conservative estimates for the upper and lower bounds to the globule-torus transition region are found. These are then used to demonstrate that the polymer globule undergoes considerable changes to its overall morphology and internal packing arrangements for sti ness values outside this transition region. Using a variety of methods we characterize these globular structures as sti ness is varied.
