## 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

## Abstract The correlation between the absolute configuration and CD of aza‐ and thiaflavanone (1, 2) is discussed: the 2__R__ configuration for the laevorotatory enantiomers has been established by a comparison of their CD data with those of (__S__)‐(βˆ’)‐3.
