If the mini her of electrons, N, is even, yon can haven dosed shell (as shown ) where the occupied orbitals each contain two electron s. For an odd n nrn her of electron s, at least on e orbital rn ust be singly occupied. In the example, three orbitals are occupied by-electron s and two orbitals arc nn occupied. Th e h ighest occupied nioleciilar orbital (HOMO is t[r), and the lowest unoccupied molecular orbital (LUMO) is The example above is a singlet, a state oh total spin S=0. Exciting one electron from the HOMO to the LUMO orbital would give one ol the I ollowing excited states ... 

I still did not have suitable low-temperature instrumentation of my own to carry out the low-temperature NMR studies, but Martin Saunders at Yale did. Thus our samples now traveled the Massachusetts Turnpike from Boston to New Haven, where with Marty we were able to study solutions of the norbornyl cation at increasingly lower temperatures using his home-built variable-temperature NMR instrumentation housed in the basement of the old Yale chemistry building. We... 

A new source of safrole that Strike has just stumbled upon is in Strike s back yard. Momma comes home from the local nursery with two plants that have these enormous leaves. They are succulents and grow like crazy. Strike What ya got there Momma Momma Don t think I haven t noticed those filthy drug books you write, you sick little monkey Strike Aw c mon. Mom. Let s not get into this again. Strike doesn t... Momma Well I needed some new ground cover plants, and...sigh...I know you re into this twisted licorice thing...so I bought these weeds that are called Licorice Plants. ... 

However well you filtered before it s time to stop the distillation and clean everything up before you distil your product. The condenser will be full of shite. Clean all your bits and replace the flask with stirring and begin to heat As I said before if you haven t got a vacuum available that s 10mm or less don t bother. 

If you haven t al ready made models of the C5H12 isomers this would be a good time to do so... 

Let s begin with a simple example Suppose you wanted to prepare cyclohexane given cyclohexanol as the starting material We haven t encountered any reactions so far that permit us to carry out this conversion m a single step...

Pollution Prevention. Procedures haven been developed for recovery of composite ammonium perchlorate propellant from rocket motors, and the treatment of scrap and recovered propellant to reclaim ingredients. These include the use of high pressure water jets or compounds such as ammonia, which form fluids under pressure at elevated temperature, to remove the propellant from the motor, extraction of the ammonium perchlorate with solvents such as water or ammonia as a critical fluid, recrystalli2ation of the perchlorate and reuse in composite propellant or in slurry explosives or conversion to perchloric acid (166,167).
