## Abstract Two brominated sesquiterpenes, majapolene B (**1**) and acetylmajapolene B (**2**), isolated from the red algal genus __Laurencia__ were investigated using vibrational circular dichroism (VCD). The ab initio theoretical VCD and IR calculations of **1** and **2** were performed by densit
