I have a question about something that has been bothering me for a while...
In all of my chemistry classes, my professors have always told me that it is impossible to predict which way a chiral molecule will rotate plane-polarized light (i.e., you will see if a molecule is D or L, but, saying you know it's structure, you have no way to tell whether it is R or S). I understand that the R/S configuration is arbitrary, just a way of naming things, but I was wondering if it is actually possible (via computer modeling or something similar) to look at a given chiral molecule's structure and predict its chirality. It seems strange to me that we have no way of knowing this other than experimentation.
Thanks very much for any information in advance :) Sorry if this is very random :)
