Austin model I

Semiempirical methods that also include the a electrons have been developed and are referred to as INDO and CNDO. NDO stands for Neglect of Differential Overlap. We will not treat these approximations here. C in CNDO stands for Complete and I in INDO stands for Intermediate. Approximations where /S is added at the end mean that the parametrization is relevant for the description of excited states and that Cl is used. AMI (Austin model 1) and PM3 (Parametrized model 3) are more recent models that build on the NDO approximation and are still in use. The AMI (developed by M. J. S. Dewar) and PM3 (developed by J. J. P. Stewart) methods are useful to get quick results on comparatively large systems. PM3 in particular has been extensively used in this book, mainly for illustration purposes.

An HPLC pump, Kontron Model 410 (Kontron Electrolab, London, UK) was used for most runs. An FMI Lab Pump Model QD-2 (Fluid Metering, Inc., Oysterbay, NY, USA) was used for the fast steric analysis of Figure lb and for flushing the channel to keep it clean. The eluted samples were monitored by an Altex model 153 (Beckman Instrument, Fullerton, CA, USA) UV detector for Channel I and by a Spectroflow Monitor SF770 (Kratos Analytical Instruments, Westwood, NJ, USA) UV detector for Channel II. A strip chart recorder from Houston Instrument Corp.(Austin, TX, USA) was used.
