Implementing AP chemistry new curriculum one year early

I am seriously thinking of trying out the new curriculum next year or maybe just part of it. Eliminating quantum and adding a couple of things.

I was too - especially colligative properties and quantum numbers.  We will have to keep solubility rules and reactions.  Not sure about the Nernst equation.  I like to use the Nernst equation to justify with a voltage will increase or decrease with non-standard conditions so will likely keep it in for qualitative purposes.

I will eliminate quantum, have already unfortunately stopped colligative properties, I will keep Nernst and Arrhenius because I like them and the students really get a good understanding of Activation Energy.  I need to add more detail  PES for mass spec  I will still refer to exceptions to Aufbau. Still mention hybridization as help for VSEPR. I will still definitely teach Henderson-Hasselbach as it works and makes thing so much simpler to understand!  Do not like all the biology implications.

I really am not sure what is meant by this statement? Can you help me out???

The student can justify the selection of a particular type of spectroscopy to measure properties associated with vibrational or electronic motions of molecules’

I have heard however, on the AP Chem listserv, that AP Bio people did that and there was a FR question on one of the topics that is being eliminated next year.  It burned some bio teachers.  How much quantum is being eliminated?  I have not examined the documents in detail.

I am going to keep Nernst and Arrhenius as well.  The curriculum is big on models and I think it is important to teach exceptions that illustrate that our models sometimes break down.  Not enthusiastic about incorporating PES - I would prefer they had focussed IR (vibrational energy), NMR, Mass Spec, and UV/VIS (electronic motions).  I think your last statement indicates they need to at least know the names of these techniques - I had not picked up on that yet.
