WebChirality is an important geometric property relating to a molecule's symmetry. A chiral molecule is non-superimposable with its mirror image, and has a "handedness" (think of shoes, which specifically go with a right or left foot). An achiral molecule is superimposable with its mirror image and do not have "handedness" (think of a baseball bat ... WebDifferentiation was accomplished through a chiral discrimination factor, R, which compares an ion ratio in a spectrum of one epimer or isomer to the same ion ratio in the spectrum of a different epimer. The R values obtained using CTD are as robust and significant as other fragmentation techniques, like radical directed dissociation (RDD).
