For 10 points, identify this set of rules, which are sometimes also named for the people who categorized them, Mary and Louis Fieser.
One generally observes a hypsochromic shift when applying these to systems without planarity, while a bathochromic shift is observed when these are applied to coplanar systems exhibiting ring strain. They are also not very accurate when applied to systems exhibiting considerable branching. Their namesake, along with Moffit, Moscowitz, Klyne, and Djerassi published the "octant rule," which were correlations between the ORD (*) spectra of saturated ketones and their structures, and 5 nm are added for exocyclic double bonds according to them. They assign a value of 217 nanometers for conjugated dienes and , thus making them useful for predicting the wavelength of peak absorption for a chromophore in UV-Vis spectroscopy.
