2 ACKNOWLEDGMENTS  Prof. S.K. Gupta is the inspiring force behind these set of slides. I had a lot to learn from his meticulous planning of the AML 120 course.  Prof. R.K. Pandey has always been there to offer me help on all aspects, in spite of his busy commitments.  Dr. Rajesh Prasad has been the source of knowledge for many of the slides in this presentation. Without his consistent guidance I would not be able to teach this course as presented.

These aren’t really ‘properties’ – more like definitions that relate to what’s happening microscopically. The goal here is to relate structure to properties.
