QUESTION 55
The likelihood that the longer elution times (Rf) were due to the following:
O The more polar head groups
a stronger interaction between the stationary phase and the lipid portion of the molecules.
The long fatty acid tails
QUESTION 56
Using the 1,3 butadiene system and UV-spectroscopy we found that exciting an electron from the(E2) HOMO to (E3) LUMO resulted in an experimental
wavelength absorption at 217 nm; whereas ,if we solved this using the particle in the box our calculated value would be 220 nm.
n?h?
En =
8ml 2
If we use formula(s) for the particle in the box, what would "L" represent for the butadiene system?
O Bond lengths associated with the entire molecule.
The sum of the bond angles associated with the molecule.
Both bond lengths and angles.
