CHEM 400: This course is an attempt to present the basic fundamentals of computational chemistry and the theoretical methodology currently available to tackle practical problems in chemistry, material sciences and bio-disciplines. The material covered will include theoretical initio and semi-empirical methods. The course will involves recitation lectures and computational experiments in campus and possible off- campus computational resources. A lot of effort is put in presenting the material hopefully in a way that would be interesting, comprehensible and enjoyable to all students with a background of one year of college calculus and physics.
